Studies of excited charm and beauty mesons at LHCb
نویسنده
چکیده
The LHCb detector is a general purpose forward spectrometer at the Large Hadron Collider, which exploits the ≈ 300 μb cross-section for bb̄ production and ≈ 6 mb cross-section for cc̄ production in 7 TeV proton-proton collisions to make precise measurements of the properties of heavy flavour hadrons. Studies of excited B and D mesons using a dataset corresponding to 1 fb−1 of integrated luminosity are presented. Measurements of masses, widths, and branching fractions are reported, as well as the first observation of the decay Bs2(5840) 0 → B∗+K−. This decay mode is then exploited in order to perform the world’s most precise measurement of the B∗−B mass difference.

Heavy Quark Production and Spectroscopy at HERA
Production of final states containing open charm (c) and beauty (b) quarks at HERA is reviewed. Photoproduction (PHP) of the charm meson resonances D∗, D and Ds, as well as D∗ production in the deep inelastic scattering (DIS) regime, are measured and compared to QCD predictions. The excited charm mesons D 1(2420), D ∗0 2 (2460) and D ± s1(2536) have been observed and the rates of charm quarks h...

LHCb is a dedicated flavor physics experiment that will observe the 14TeV proton–proton collisions at CERN’s Large Hadron Collider (LHC). Construction of the LHCb detector is near completion, commissioning of the detector is well underway, and LHCb will be fully operational and ready to take data in advance of the projected May 2008 turn-on date for the LHC. The LHCb software trigger will featu...
متن کاملCharm fragmentation and excited charm and charm-strange mesons at ZEUS
Charm hadrons were produced copiously in ep collisions with a centre-of-mass energy of 318GeV at HERA providing a means to study charm hadronisation. During first phase of the HERA operation (1992-2000), the ZEUS collaboration accumulated data sample corresponding to an integrated luminosity of ∼ 120 pb. Measurements of the D, D, D and Λc production a with the HERA I data were used to determine...

We calculate the spectrum of the charm-beauty mesons using the relativized quark model. Using the wavefunctions from this model we compute the radiative widths of excited cb̄ states. The hadronic transition rates between cb̄ states are estimated using the Kuang-Yan approach and are combined with the radiative widths to give estimates of the relative branching ratios. These results are combined wi...
متن کاملExperimental constraints from flavour changing processes and physics beyond the Standard Model
Flavour physics has a long tradition of paving the way for direct discoveries of new particles and interactions. Results over the last decade have placed stringent bounds on the parameter space of physics beyond the Standard Model. Early results from the LHC, and its dedicated flavour factory LHCb, have further tightened these constraints and reiterate the ongoing relevance of flavour studies. ...
