The performance of the LHCb Muon system and its stability across full 2010 data taking with LHC running at ps = 7 TeV energy is studied. optimization detector setting time calibration performed first collisions delivered by described. Particle rates, measured for wide range luminosities beam operation conditions experienced during run, are compared values expected from simulation. space alignment detectors, chamber efficiency, resolution cluster size evaluated. found to be as specifications...
The existence of a light dark force mediator has been tested with the KLOE detector at DAPHNE. This particle, called U, is searched for using decay chain phi-->etaU, eta-->pi+pi-pi0, U-->e+e-. No evidence found in 1.5 fb-1 data. resulting exclusion plot covers mass range 5
The performance of the muon identification in LHCb is extracted from data using muons and hadrons produced J/ψ → μ+μ−, Λ0 pπ− D⋆+→π+D0(K−π+) decays. procedure based on pattern hits chambers. A momentum dependent binary requirement used to reduce probability be misidentified as level 1%, keeping efficiency range 95-98%. As further refinement, a likelihood built for non-muon hypotheses. Adding this that provides total at 93%, hadron misidentification probabilities are below 0.6%.
We have searched for a light vector boson U, the possible carrier of "dark force", with KLOE detector at DAΦNE e+e− collider, motivated by astrophysical evidence presence dark matter in Universe. Using collisions collected an integrated luminosity 239.3 pb−1, we look dimuon mass peak reaction e+e−→μ+μ−γ, corresponding to decay U→μ+μ−. find no U signal. set 90% CL upper limit mixing parameter squared between photon and 1.6×10−5 8.6×10−7 region 520<mU<980 MeV.
Upgrades to the LHCb computing infrastructure in first long shutdown of LHC have allowed for high quality decay information be calculated by software trigger making a separate offline event reconstruction unnecessary. Furthermore, storage space triggered candidate is an order magnitude smaller than entire raw that would otherwise need persisted. Tesla, following renowned physicist naming convention, application designed process trigger, with resulting output used directly perform physics...
Neutral kaon pairs produced in phi decays anti-symmetric entangled state can be exploited to search for violation of CPT symmetry and Lorentz invariance. We present an analysis the CP-violating process phi->K_S K_L->pi+pi-pi+pi- based on 1.7 fb-1 data collected by KLOE experiment at Frascati phi-factory DAFNE. The are used perform a measurement CPT-violating parameters Delta_amu neutral kaons contest Standard Model Extension framework. measured reference frame fixed stars are: Delta_ao =...
Since 2015, with the restart of LHC for its second run data taking, LHCb experiment has been empowered a dedicated computing model to select and analyse calibration samples measure performance particle identification (PID) detectors algorithms. The novel technique was developed within framework innovative trigger experiment, which relies on online event reconstruction most datasets, reserving offline special physics cases. strategy process samples, includes data-processing scheme combining...
