Two short explored links of performance art in North America
No full text[EN] Is there a performance art pedagogy? Are there many? Can performance art be taught? How? These kind of questions are the ones that this text expects to trigger in the reader from a review, that doesn’t pretend to be exhaustive, of texts with perspectives that are hardly coincidental such as those proposed on one side, by Eloy Tarcisio in Dulce María de Alvarado’s Performance en México (2015): 28 testimonios 1995 – 2000 and by La Pocha Nostra in Exercises for Rebel Artists: Radical Performance Pedagogy (2011); and on the other side, by James Elkins in Why Art Cannot Be Taught: A Handbook for Art Students (2001).
Other questions that may arise are Is performance art only a learning objective? Or can it also be a tool to achieve other pedagogical purpose? It’s expected to awaken these questions from a short review of W.J.T. Mitchell’s Showing seeing: a critique of visual culture (2002) in which, even if the idea of a “performance art pedagogy” is not refuted, performance itself is proposed as a pedagogic tool to learn, particularly, about visual studies.
Finally, why is it important to relate performance art and experience? What kind of experience does a spectator have during a performance art piece? Why is representation a key concept to performance art, understood from phenomenology? Centered on Lester Embree’s Reflective analysis (2003), the taxonomy of experience proposed by this author is presented, which might be the key to explain, from other scope, a phenological one, a feature of this artistic discipline which has been highlighted by Bartolomé Ferrando’s El arte de la performance, Elementos de creación: la presencia del cuerpo (2009).[ES] ¿Existe una pedagogía de la performance? ¿Existen varias?; ¿La performance se enseña? ¿Cómo? Este tipo de preguntas son las que este texto desea provocar en el lector a partir de una revisión, que no pretende ser exhaustiva, de textos con visiones que son difícilmente coincidentes como las planteadas por un lado, por Eloy Tarcisio en Performance en México: 28 testimonios 1995 – 2000 de Dulce María de Alvarado (2015) y por La Pocha Nostra (2011) en Exercises for Rebel Artists: Radical Performance Pedagogy; y por otro lado, por James Elkins (2001) en Why Art Cannot Be Taught: A Handbook for Art Students. Otras preguntas que pueden surgir son ¿La performance es solamente un objetivo de aprendizaje? o ¿puede también ser una herramienta para alcanzar otro propósito pedagógico? Se espera despertar estas interrogantes a partir de una breve revisión de Showing seeing: a critique of visual culture de W.J.T. Mitchell (2002) en la que, si bien no se rebate la idea de “pedagogía de la performance”, se propone a la propia performance como herramienta pedagógica para aprender, particularmente, sobre estudios visuales.Finalmente, ¿por qué es importante relacionar la performance y la experiencia? ¿qué tipo de experiencia tiene un espectador durante una performance? ¿por qué la presentación es un concepto clave para la performance, comprendida desde la fenomenología? Centrados en Análisis Reflexivo de Lester Embree (2003), se presenta la taxonomía de la experiencia propuesta por este autor, la cual puede ser la clave para explicar, desde otro ámbito, uno fenomenológico, un rasgo de esta disciplina artística que ha sido destacada por Bartolomé Ferrando (2009) en El arte de la performance, Elementos de creación: la presentación.Bernal Rivas, GE.

Observation of the associated production of a single top quark and a W Boson in pp collisions at s=8 TeV.

Further distribution of this work must maintain attribution to the author(s) and the published articles title, journal citation, and DOI.The first observation of the associated production of a single top quark and a W boson is presented. The analysis is based on a data set corresponding to an integrated luminosity of 12.2 fb^{-1} of proton-proton collisions at sqrt[s]=8 TeV recorded by the CMS experiment at the LHC. Events with two leptons and a jet originating from a b quark are selected. A multivariate analysis based on kinematic and topological properties is used to separate the signal from the dominant tt[over ¯] background. An excess consistent with the signal hypothesis is observed, with a significance which corresponds to 6.1 standard deviations above a background-only hypothesis. The measured production cross section is 23.4±5.4 pb, in agreement with the standard model prediction
Measurement of the ratio of inclusive jet cross sections using the anti- kT algorithm with radius parameters R=0.5 and 0.7 in pp collisions at s =7 TeV

Further distribution of this work must maintain attribution to the author(s) and the published articles title, journal citation, and DOI.Measurements of the inclusive jet cross section with the anti-kT clustering algorithm are presented for two radius parameters, R=0.5 and 0.7. They are based on data from LHC proton-proton collisions at s=7TeV corresponding to an integrated luminosity of 5.0fb-1 collected with the CMS detector in 2011. The ratio of these two measurements is obtained as a function of the rapidity and transverse momentum of the jets. Significant discrepancies are found comparing the data to leading-order simulations and to fixed-order calculations at next-to-leading order, corrected for nonperturbative effects, whereas simulations with next-to-leading-order matrix elements matched to parton showers describe the data best

The data correspond to a total integrated luminosity of 5.0 fb−1, collected by the CMS experiment at the LHC. The tt and lepton charge asymmetries, defined as the differences in absolute values of the rapidities between the reconstructed top quarks and antiquarks and of the pseudorapidities between the positive and negative leptons, respectively, are measured to be A C = −0.010 ± 0.017 (stat.) ± 0.008 (syst.) and A lep C = 0.009 ± 0.010 (stat.) ± 0.006 (syst.). The lepton charge asymmetry is also measured as a function of the invariant mass, rapidity, and transverse momentum of the tt ¯ system. All measurements are consistent with the expectations of the standard model.BMWF and FWF (Austria); FNRS and FWO (Belgium); CNPq, CAPES, FAPERJ, and

Search for anomalous production of events with three or more leptons in pp collisions at √s = 8TeV
No full textPublished by the American Physical Society under the terms of the Creative Commons Attribution 3.0 License. Further distribution of this work must maintain attribution to the author(s) and the published articles title, journal citation, and DOI.A search for physics beyond the standard model in events with at least three leptons is presented. The data sample, corresponding to an integrated luminosity of 19.5fb-1 of proton-proton collisions with center-of-mass energy s=8TeV, was collected by the CMS experiment at the LHC during 2012. The data are divided into exclusive categories based on the number of leptons and their flavor, the presence or absence of an opposite-sign, same-flavor lepton pair (OSSF), the invariant mass of the OSSF pair, the presence or absence of a tagged bottom-quark jet, the number of identified hadronically decaying τ leptons, and the magnitude of the missing transverse energy and of the scalar sum of jet transverse momenta. The numbers of observed events are found to be consistent with the expected numbers from standard model processes, and limits are placed on new-physics scenarios that yield multilepton final states. In particular, scenarios that predict Higgs boson production in the context of supersymmetric decay chains are examined. We also place a 95% confidence level upper limit of 1.3% on the branching fraction for the decay of a top quark to a charm quark and a Higgs boson (t→cH), which translates to a bound on the left- and right-handed top-charm flavor-violating Higgs Yukawa couplings, λtcH and λctH, respectively, of |λtcH|2+|λctH|2<0.21
Search for WWγ and WZγ production and constraints on anomalous quartic gauge couplings in pp collisions at s=8 TeV
No full textPublished by the American Physical Society under the terms of the Creative Commons Attribution 3.0 License. Further distribution of this work must maintain attribution to the author(s) and the published articles title, journal citation, and DOI.A search for WVγ triple vector boson production is presented based on events containing a W boson decaying to a muon or an electron and a neutrino, a second V (W or Z) boson, and a photon. The data correspond to an integrated luminosity of 19.3 fb−1 collected in 2012 with the CMS detector at the LHC in pp collisions at s=8 TeV. An upper limit of 311 fb on the cross section for the WVγ production process is obtained at 95% confidence level for photons with a transverse energy above 30 GeV and with an absolute value of pseudorapidity of less than 1.44. This limit is approximately a factor of 3.4 larger than the standard model predictions that are based on next-to-leading order QCD calculations. Since no evidence of anomalous WWγγ or WWZγ quartic gauge boson couplings is found, this paper presents the first experimental limits on the dimension-eight parameter fT,0 and the CP-conserving WWZγ parameters κ0W and κCW. Limits are also obtained for the WWγγ parameters a0W and aCW.BMWFW and FWF (Austria); FNRS and FWO (Belgium); CNPq, CAPES, FAPERJ, and FAPESP (Brazil); MES (Bulgaria); CERN; CAS, MoST, and NSFC (China); COLCIENCIAS (Colombia); MSES and CSF (Croatia); RPF (Cyprus); MoER, SF0690030s09 and ERDF (Estonia); Academy of Finland, MEC, and HIP (Finland); CEA and CNRS/ IN2P3 (France); BMBF, DFG, and HGF (Germany); GSRT (Greece); OTKA and NIH (Hungary); DAE and DST (India); IPM (Iran); SFI (Ireland); INFN (Italy); NRF and WCU (Republic of Korea); LAS (Lithuania); MOE and UM (Malaysia); CINVESTAV, CONACYT, SEP, and UASLP-FAI (Mexico); MBIE (New Zealand); PAEC (Pakistan); MSHE and NSC (Poland); FCT (Portugal); JINR (Dubna); MON, RosAtom, RAS and RFBR (Russia); MESTD (Serbia); SEIDI and CPAN (Spain); Swiss Funding Agencies (Switzerland); MST (Taipei); ThEPCenter, IPST, STAR and NSTDA (Thailand); TUBITAK and TAEK (Turkey); NASU and SFFR (Ukraine); STFC (United Kingdom); DOE and NSF (USA)
Measurement of the muon charge asymmetry in inclusive pp →W + X production at s=7 TeV and an improved determination of light parton distribution functions
No full textPublished by the American Physical Society under the terms of the Creative Commons Attribution 3.0 License. Further distribution of this work must maintain attribution to the author(s) and the published articles title, journal citation, and DOI.Measurements of the muon charge asymmetry in inclusive pp → W + X production at root s= 7 TeV are
presented. The data sample corresponds to an integrated luminosity of 4.7 fb−1 recorded with the CMS
detector at the LHC. With a sample of more than 20 million W → μν events, the statistical precision is
greatly improved in comparison to previous measurements. These new results provide additional
constraints on the parton distribution functions of the proton in the range of the Bjorken scaling variable
x from 10−3 to 10−1. These measurements and the recent CMS measurement of associated W þ charm
production are used together with the cross sections for inclusive deep inelastic e p scattering at HERA in
a next-to-leading-order QCD analysis. The determination of the valence quark distributions is improved,
and the strange-quark distribution is probed directly through the leading-order process g þ s → W þ c in
