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 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 studied the phi->a_0(980) gamma process with KLOE detector at Frascati phi-factory DAPhNE by detecting phi->eta pi^0 decays in final states eta->gamma and eta->pi^+ pi^- pi^0. measured branching ratios for both states: Br(phi->eta gamma)=(7.01 +/- 0.10 0.20)x10^-5 (7.12 0.13 0.22)x10^-5 respectively. also extracted a_0(980) mass its couplings to eta pi^0, K^+ K^-, phi meson from fit of invariant distributions using different phenomenological models.

We present a precise measurement of the ratio R K =Γ(K→e ν(γ))/Γ(K→μ ν(γ)) and study radiative process K→e ν γ, performed with KLOE detector. The results are based on data collected at Frascati e + − collider DAΦNE for an integrated luminosity 2.2 fb−1. find =(2.493±0.025stat±0.019syst)×10−5, in agreement Standard Model expectation. This result is used to improve constraints parameters Minimal Supersymmetric lepton flavor violation. also measured differential decay rate dΓ(K→e γ)/dE γ photon...

Six of the key physics measurements that will be made by LHCb experiment, concerning CP asymmetries and rare B decays, are discussed in detail. The "road map" towards precision is presented, including use control channels other techniques to understand performance detector with first data from LHC.

We report the first observation of rare eta->e+e-e+e- decay based on 1.7 fb^{-1} collected by KLOE experiment at DAFNE phi-factory. The selection e+e-e+e- final state is fully inclusive radiation. have identified 362 +- 29 events resulting in a branching ratio (2.4 0.2_stat+bckg 0.1_syst) x 10^{-5}.
