LHCb has collected the world's largest sample of charmed hadrons. This sample is used to search for direct and
indirect CP violation in charm, and to measure $D^0$ mixing parameters. New updated measurements from several
decay modes are presented, with complementary time-dependent and time-integrated analyses.

The study of CP violation in Bs oscillations is one of the key goals of the LHCb experiment. Effects are predicted to be very small in the Standard Model but can be significantly enhanced in many models of new physics. We present the world’s best measurement of the CP-violating phase φs using B0s → J/ψφ and B0s → J/ψππ decays, B0s → φφ and B->hh (h=K,pi).

Decays of b-hadrons without charmed particles in the final state offer rich opportunities to test the Standard Model. For example, CP violation in charmless charged two-body and three-body B decays provides ways to measure the CKM angle $\gamma$ and to search for New Physics. The angular distributions of decays to vector-vector final states provide additional interesting observables. We...

B->DX decays provide a tree-diagram only determination of the angle γ of the CKM unitarity triangle, which remains the least precisely measured parameter of the CKM mixing matrix. While several new results provide updated measurements of this angle, some decay channels with sensitivity to gamma have only recently been observed. Other measurements in the rich B to open charm phenomenology are...

The Bc meson is the only weakly decaying doubly heavy meson, which makes it an very interesting system to study.
LHCb has recently measured its lifetime, mass and many decay channels, including for the first time a decay of the c-quark.

This talk will begin with an overview of the ATLAS detector with emphasis on B-physics. A selection of recently approved ATLAS B-physics analyses, including a measurement of parity violation asymmetry parameter $\alpha_b$ and helicity amplitudes for the decay $\Lambda^0_b \rightarrow J/\psi \Lambda^0$ using 4.6 fb$^{−1}$ of proton-proton collision data in 2011, will be presented.

Radiative decays allow the measurement of the photon polarisation and thus test the left-handed couplings in weak interactions.
Recent LHCb measurements have shown a non-zero polarisation. The interpretation of this result in terms of right-handed couplings requires more theoretical input.
