Extensions of the Standard Model (SM) featuring warped extra dimensions (Randall-Sundrum models) have a build-in protection mechanism, called RS-GIM, which prevents the occurrence of large flavor changing neutral currents. This mechanism is extremely successful and brings the RS model into agreement with a new physics scale of a few TeV in almost all flavor sectors. The single exception is CP...

The decay mode $B^0_s \to D_s^\pm K^\mp$ allows for one of the theoretically cleanest time dependent measurements of the CKM angle $\gamma$. This contribution reports the observation of this decay mode at LHCb and the measurement of its world best measurement branching fraction relative to the Cabibbo--favoured mode $B^0_s \to D_s^-\pi^+$
based on data sample of 0.37 $\rm fb^{-1}$...

After a short motivation to look for K^+ -> pi^+ pi^0 gamma we report improvements made on its theoretical description and exemplify its efficiency to constrain New Physics.

In a sample of 471 million BB events collected with the BABAR detector at the PEPII e+e- collider we study the rare decays B->K(*)l+l-, where l+l- is either e+e- or mu+mu-. We report results on partial branching fractions and isospin asymmetries in six bins of di-lepton mass squared. We further present CP and lepton-flavor symmetries for di-lepton masses below and above the J/Psi resonance. We...

In this talk, the measurement of the branching fraction, polarization, and time-dependent CP-violation in $B^0 \to D^{*+} D^{*-}$ decays will be presented. It was performed with a data sample of 772 million $B \bar{B}$ pairs, collected with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider.
The time-dependent CP-violation in this $b \to c \bar{c} d$ transition is directly...

Measurements of the polarization amplitudes are presented using a time integrated analysis for the decay B_s to phi phi using data collected by the LHCb experiment between March and November 2011. Also presented are measurements of T-violating triple product asymmetries, which if observed to be significantly different from zero could indicate the presence of new physics.

Icarus is the largest liquid Argon TPC detector ever built (~600 ton LAr mass). It operates underground at the LNGS laboratory in Gran Sasso. It has been smoothly running since summer 2010, collecting data with the CNGS beam and with cosmics. Liquid argon TPCs are really ``electronic bubble chambers'' providing a completely uniform imaging and calorimetry with unprecedented accuracy on massive...
