LHCb Detector Momentum Calibration with the First Year Data and a Performance Study of CP Violation Measurement with the B°s -> J/[Psi][Phi] Decays

A new area in particle physics has begun with the start of the Large Hadron Collider (LHC) at CERN at the end of 2009, which collides protons at energies never reached before. To detect the products of the collisions, four main experiments are located arou ...

Precise measurement of hadronic τ-decays with an η meson

Olivier Schneider, Chao Wang, Tagir Aushev, Sun Hee Kim, Remi Léandre Albert Louvot, Xiao Wang

We have studied hadronic τ decay modes involving an η meson using 490 fb-1 of data collected with the Belle detector at the KEKB asymmetric-energy e+ e- collider. The following branching fractions have been measured: B (τ- → K- η ντ) = (1.58 ± 0.05 ± 0.09) ...

We search for lepton-flavor-violating τ decays into a lepton (electron or muon) and an f0 (980) meson using 671 fb-1 of data collected with the Belle detector at the KEKB asymmetric-energy e+ e- collider. No events are observed and we set the following 90% ...

Recently, many unexpected new particles were discovered with masses around 4 GeV/c2. They are collectively called XYΖ mesons and while some of them have been identified as charmonium states, many others have properties that don't fit into the quark-antiqua ...

We present a measurement of the branching fraction B(Ds+→μ+νμ ) using a 548fb-1 data sample collected by the Belle experiment at the KEKB e+e- collider. The Ds momentum is determined by reconstruction of the system recoiling against DKγX in events of the t ...

We study the three-body charmed baryonic decays B̄0→Σ c++p̄π- and B̄0→Σc0p̄π+ in the four-body final state B̄0→Λc+p̄π+π-, using a data sample of 357fb-1 accumulated at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. ...

We have searched for lepton-flavor-violating τ decays with a pseudoscalar meson (η, η′ and π0) using a data sample of 401 fb-1 collected with the Belle detector at the KEKB asymmetric-energy e+ e- collider. No evidence for these decays is found and we set ...

Direct search for Higgs boson in LHCb and contribution to the development of the vertex detector

Laurent Locatelli

The LHCb experiment (Large Hadron Collider beauty) is one of the four experiments under construction at the LHC (Large Hadron Collider) at CERN near Geneva. It is planned to start in 2007 and its goal is the study of b-quark physics. The LHC is a circular ...

Measurement of the branching fraction, polarization, and CP asymmetry for B0→ρ+ρ- Decays, and determination of the cabibbo-kobayashi-maskawa phase 2

Olivier Schneider, Aurelio Bay, Stewart Cole, Mingkui Wang, Chao Wang, Tagir Aushev, Lei Zhang, Vladislav Balagura, Sun Hee Kim, Jing Li

We have measured the branching fraction B, longitudinal polarization fraction fL, and CP asymmetry coefficients A and S for B0→ρ+ρ- decays with the Belle detector at the KEKB e+e- collider using 253fb-1 of data. We obtain B=[22.8±3.8(stat)-2.6+2.3(syst)]×1 ...
