Production and spectroscopy of open-flavoured hadrons at hadron colliders
No full textStudies on the production and spectroscopy of heavy hadrons provide important inputs to test the reliability of several models and techniques. Recent results on the production of the charmed and beauty mesons and baryons at hadron colliders are summarized. The observations of new excited heavy hadrons and new decays are also presented
Charm Dalitz Analyses at BaBar
No full textDalitz plot analyses of D{sup 0} events reconstructed for the hadronic decay D{sup 0} {yields} {bar K}{sup 0}K{sup +}K{sup -} and D{sup 0} {yields} {bar K}{sup 0}{pi}{sup +}{pi}{sup -} are presented here. The analyses are based on a data sample of 91.5 fb{sup -1}. All data have been collected with the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} storage rings at SLAC running at center-of-mass energies on and 40 MeV below the {Upsilon}(4S) resonance
LHCb results on exotics and pentaquark states
No full textThe latest years have seen a resurrection of interest in searches for
exotic states. Using the data collected at pp collisions at 7 and 8 TeV
by the LHCb experiment, unambiguous new observations of exotic charmonia
hadrons produced in B and Lambda(b) decays are presented. Results of a
search for a tetraquark state decaying into B-s(0)pi(+/-) arealso
reported
Measurement of the CKM angle γ from a combination of LHCb results
No full textA combination of measurements sensitive to the CKM angle γ from LHCb is performed. The inputs are from analyses of time-integrated B+ → DK+, B0 → DK∗0, B0 → DK+π− ; B+ → DK+π+π− tree-level decays. In addition, results from a time-dependent analysis of Bs 0 → Ds ∓K± decays are included. The combination yields γ = (72. 2− 7.3 + 6.8)°, where the uncertainty includes systematic effects. The 95.5% confidence level interval is determined to be γ ∈ [55.9, 85.2]°. A second combination is investigated, also including measurements from B+ → Dπ+ ; B+ → Dπ+π−π+ decays, which yields compatible results.[Figure not available: see fulltext.] © 2016, The Author(s)

No full textMenu for Al Pappagallo restaurant in Bologna listing soups, dishes, wines, desserts, drinks, and specials offered by the restaurant along with itemized prices. The front of the menu features a color painting of an outdoor cafe scene beneath a tall building arch. Patrons are seated around small tables wearing hats and formal clothing. A waiter in a white coat offers a drink to a table in the center of the painting. The logo for "Cinzano" wine is superimposed on top of the painting
Dalitz plot analysis of D0 → K0K +K- ; DsJ states at BaBar
No full textA Dalitz plot analysis of D0 events reconstructed in the hadronic decay D0 → K0K+K- is presented here. The analysis is based on a data sample of 91.5 fb- 1 . Herewith enclosed is an updated, preliminary analysis of DsJ states using 125 fb-1 . All data have been collected with the BABAR detector at the PEP-II asymmetric-energy e+e- storage rings at SLAC running at center-of-mass energies on ; 40 MeV below the Υ(4S) resonance.

Charmed meson decays: Theoretical overview ; experimental results
No full textThe study of the charmed meson decays is getting a renewable interest because it provides a critical input to the CKM-γ measurements. In addition the discovery of new physics can be revealed in the search for the mixing ; CP violation ; the large coupling to the light mesons makes charm decays an important probe of light meson spectroscopy. The Dalitz plot technique ; a selection of recent experimental results are briefly reviewed. © Società Italiana di Fisica
