Evidence of time-dependent CP violation in the decay B^{0}→D^{+}D^{-}

Olivier Schneider, Aurelio Bay, Chao Wang, Tagir Aushev, Vladislav Balagura, Jean Wicht, Remi Léandre Albert Louvot, Nicolas Zwahlen, Jing Li

We report a measurement of the CP-odd fraction and the time-dependent CP violation in B-0 -> D*+D*- decays, using 657x10(6) BB events collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We measure ...

Contribution to the inner tracker design and penguin sensitivity studies for the measurement of sin 2ß in LHCb

Aurélie Perrin

LHCb is one of the four large experiments hosted at the Large Hadron Collider (LHC) at CERN in Geneva. It will start taking data in September 2008, and will then operate for several years. It consists of a single-arm forward spectrometer dedicated to preci ...

Изучение поляризации фотона в распаде $B_{s} \to \phi\gamma$ детекторе LHCb

Lesya Shchutska

The thesis is dedicated to the Monte Carlo analysis of the radiative decay Bs->phi gamma at LHCb. The main attention is drawn to the study of the photon polarization measurement through the CP-violating effects. The statistical error of the CP-violation pa ...

Evidence for D0-D̄0 mixing

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

We observe evidence for D0-D̄0 mixing by measuring the difference in the apparent lifetime when a D0 meson decays to the CP eigenstates K+K- and π+π- and when it decays to the final state K-π+. We find the relative difference of the lifetimes yCP to be [1. ...

B°s -> J/[psi] [eta] decays and sensitivity to the B°s mixing at LHCb

The LHCb experiment will be installed in the proton-proton Large Hadron Collider (LHC) at CERN, Geneva. The detector is a single arm spectrometer currently under construction: LHC running and LHCb data taking will start in 2007. LHCb will then benefit from ...

Study of time-dependent CP violation in B0 → J/ Ψπ0 decays 261801

Aurelio Bay, Tagir Aushev, Jing Li

The CP asymmetry parameters in the decay B0(B̄0) → J/ψπ0, were described. The measurement of the CP asymmetry parameters was based on a 140 fb-1 data sample, which was accumulated at the γ(4S) resonance by the Belle detector at the KEKB asymmetric-energy e ...

Observation of large CP violation and evidence for direct CP violation in B0 → π+ π- decays

Aurelio Bay, Stewart Cole, Tagir Aushev, Sun Hee Kim, Ji Hyun Kim, Sanjeev Kumar, Jing Li

The CP violation parameters in Bo → π +π- decay were investigated. The flavor of the accompanying B meson was identified by reconstructing B o→π+π- CP eigenstate. It was observed that the expected sensitivity was optimized using the ratio LR. The study sho ...

Parity-violating electron deuteron scattering and the proton's neutral weak axial vector form factor

Andreea Veronica Savu, Dipanwita Dutta

We report on a new measurement of the parity-violating asymmetry in quasielastic electron scattering from the deuteron at backward angles at Q(2)=0.038 (GeV/c)(2). This quantity provides a determination of the neutral weak axial vector form factor of the n ...

CP Violation Beyond the Standard Model

Riccardo Rattazzi

We review CP violation in various extensions of the electroweak sector of the Standard Model. A particular emphasis is put on supersymmetric models. We describe the two CP problems of supersymmetry, concerning

d_N

and

\epsilon_K

. We critically review t ...
