Measurement of the B [ + over c ] meson lifetime using B [ + over c
نویسندگان
چکیده
The lifetime of the B+ c meson is measured using semileptonic decays having a J/ψ meson and a muon in the final state. The data, corresponding to an integrated luminosity of 2 fb−1, are collected by the LHCb detector in pp collisions at a centre-of-mass energy of 8 TeV. The measured lifetime is τ = 509± 8± 12 fs, where the first uncertainty is statistical and the second is systematic.

متن کاملComparing the Behavior Hydrodynamics Flow Over of Type A, B, and C Piano Key Weirs
The piano key weir (PKW) is a new type of hydraulic structure that has been of great interest to designers in recent years. In the present study, steady flow on the types A, B, and C PKWs was studied numerically using the FLOW-3D numerical model. Upon software validation using the experimental data, the 3D flow pattern on the types A, B, and C PKWs was studied, and along with the evaluation of ...
متن کاملClassification of hydrometeors using microwave brightness temperature data from AMSU-B over Iran
The Advanced Microwave Sounding Unit-B (AMSU-B) installed on the NOAA-15, 16, and 17 satellites, is the new generation of a series of microwave imagers/sounders that can sense atmospheric moisture and other hydrometeors through clouds. This paper demonstrates the potential of multi-frequency AMSU-B data for classifying different types of hydrometeors. Ten types of these hydrometers have been co...
متن کاملEffects of final state interaction in B^+_c to D^0 K^+ decay
In this paper, the decay of Bc+ meson, which consists of two b and c heavy quarks, into the Do and K+ mesons was studied. Given that the experimental branching ratio for this decay was within the range of 3.75*10-5 to 11.16*10-5; it was decided to calculate the theoretical branching ratio by applying the final state interaction (FSI) through the T and cross-section channels. In this process, b...
