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 measured the fully inclusive K+ -> mu+nu(gamma) absolute branching ratio with KLOE experiment at DAFNE, Frascati Phi-factory. From some 865,283 decays obtained from a sample of about 5.2x10^8 Phi-meson decays, we find BR(K+ mu+ nu (gamma)) = 0.6366 +-0.0009(stat.) +-0.0015(syst.), corresponding to an overall fractional error 0.27%. Using recent lattice results on decay constants pseudoscalar mesons one can obtain estimate for CKM mixing matrix element |Vus|=0.2223+-0.0026.
The increasing use of mobile phones and wireless networks raised a great debate about the real carcinogenic potential radiofrequency-electromagnetic field (RF-EMF) exposure associated with these devices. Conflicting results are reported by majority in vivo vitro studies on capability RF-EMF to induce DNA damage mutations mammalian systems. Aimed at understanding whether less ambiguous responses might be evidenced plant systems respect ones, present work mutagenic effect has been studied...
We present a measurement of the KL lifetime using KLOE detector. From sample 4 x 10^8 KS pairs following reaction e+ e- -> phi we select 15 10^6 p0 decays tagged by pi+ pi- events. fit proper time distribution find tau_L = (50.92 +- 0.17{stat} 0.25{syst})$ ns. This is most precise performed to date.
