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.
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.
The ATLAS Level-1 Muon Barrel Trigger is one of the main elements first stage event selection experiment at Large Hadron Collider. challenge system a reduction rate from collision 40 MHz by factor 103, using simple algorithms that can be executed in highly parallel custom electronics with latency order 1 μs. input consists an array processors receiving full granularity data dedicated detector (Resistive Plate Chambers Barrel). This algorithm performed directly on-detector, while final boards...
We present a measurement of the branching ratio CP violating decay KL->pi+pi- performed by KLOE experiment at phi factory DAFNE. use 328 pb-1 data collected in 2001 and 2002, corresponding to ~ 150 million tagged KL mesons. find BR(KL->pi+pi-) = $(1.963 +/- 0.012 0.017)x 10^-3. This is fully inclusive final-state radiation. Using above result, we determine modulus amplitude |\eta_{+-}| be (2.219 0.013)x 10^{-3} |\epsilon| (2.216 10^{-3}.
The ATLAS barrel level-1 muon trigger processes hit information from the resistive plate chamber detector, identifying candidate tracks and assigning them to a programmable p/sub T/ range unique bunch crossing number. system uses up seven detector layers seeks patterns compatible with in bending nonbending projection. basic principle of algorithm is demand coincidence hits different within path. width road related threshold be applied. split into an on-detector off-detector part. electronics...
The phi-meson leptonic widths, Gee and Gmm, are obtained, respectively, from the e+e- forward-backward asymmetry muon cross section around phi-mass energy. We find Gee=1.32⊕0.05⊕0.03 kev sqrt(GeeGmm)= 1.320⊕0.018⊕0.017 kev. These results, compatible with Gee=Gmm, provide a precise test of lepton universality. Combining two results gives G_lept=1.320⊕0.023
We have searched for the C-violating decay eta to gamma in a sample of ~ 18 million mesons produced phi decays, collected with KLOE detector at Frascati phi-factory DAFNE. No signal is observed and we obtain upper limit BR(eta gamma) less equal than 1.6x10^(-5) 90 % C.L.
