The Belle II experiment
No full textThe Belle II experiment will analyze the products of the e+e- collisions at the center-of-mass energy corresponding to the mass of the Υ(4S) produced at the high-luminosity B-Factory SuperKEKB. The experiment will collect 50 ab-1, allowing to probe the Standard Model at a never-reached level, and to put very stringent constraints in the space of parameters of many New Physics models. I report here the expected precision that Belle II will reach with the full dataset on a selection of observables in the charm and B physics sectors
Studies of CP violation and mixing in the D mesons decays from BABAR
No full textAfter an introduction on the mixing and CP violation (CPV) in the neutral charmed mesons system, we present the current status of the measurements. We discuss some recent analyses performed on the data sample collected by the BABAR detector at the PEPII e+e- asymmetric collider
Charm mixing and CP violation at BABAR
No full textWe report on the latest searches for D0 - D0 mixing and CP violation in charm decays at the BABAR experiment. We present a measurement of the lifetime ratio parameter yCP in the two-body K- K+ and p-p+ final states that excludes the no mixing hypothesis with a significance of 3.3s . A search for indirect CP violation in the same channels has also been performed. A search for CPV in the D+ ? KS0K+, D+s ? KS0 K+, D+s ? KS0 p+ and D+ ? K+ K- p+ decays is also presented. No indication of CPV in charm decays is found
Inner tracking devices at the belle II experiment
No full textIn the future Belle II experiment at the SuperKEKB collider in Tsukuba, Japan, charged particle tracking in the vicinity of the e+e- interaction point is provided by a two-layer silicon pixel detector based on the novel DEPFET technology (PXD) and by a four-layer silicon strip detector (SVD). In this presentation, I review the technology and the design of these two devices, and describe the current state of their construction
Phenomenological and Experimental Developments in Charm Physics: The WG7 Report from CKM 2016
No full textWe present an overview of recent developments in charm physics reported in the Working~Group~7 meetings of the CKM 2016 workshop. Progresses in experimental analysis and techniques were reported by LHCb, Belle, BABAR and BESIII along with projections for the future. Developments were also reported in the phenomenological extraction of both direct and indirect CP violation from data in two-, three- and four-body hadronic decays of the mesonic system
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
