On the consistency between the observed amount of CP violation in the K- and B$_d$-systems within minimal flavor violation / Buras, Andrzej J (Munich, Tech. U.) ; Guadagnoli, Diego (Munich, Tech. U. ; CERN)
We reappraise the question whether the Standard Model, and Minimal Flavor Violating (MFV) models at large, can simultaneously describe the observed CP violation in the K- and Bd-systems. We find that CP violation in the Bd-system, measured most precisely through (sin 2 beta)_{J/psi Ks}, implies |epsilon_K^{SM}| = 1.78(25) x 10^{-3} for the parameter epsilon_K, measuring indirect CP violation in the K-system, to be compared with the experimental value |epsilon_K^{exp}| = 2.23(1) x 10^{-3}. [...]

CP, T and CPT versus temporal asymmetries for entangled states of the Bd-system / Banuls, M.C. (Valencia U.) ; Bernabeu, J. (CERN)
The observables used in the K-system to characterize T and CPT violation are no longer useful for the Bd-system, since the width difference between the physical states is vanishingly small. We show that only Im(epsilon) and Re(delta) can survive if Delta Gamma=0, and build alternative CP-odd, CPT-odd, T-odd and temporal asymmetries for the (B_CP -> B0, B0bar) transitions. [...]

Supersymmetry and Generic BSM Models in PYTHIA 8 / Desai, Nishita (Harish-Chandra Res. Inst.) ; Skands, Peter Z. (CERN)
We describe the implementation of supersymmetric models in PYTHIA 8, including production and decay of superparticles and allowing for violation of flavour, CP, and R-parity. We also present a framework for importing generic new-physics matrix elements into PYTHIA 8, in a way suitable for use with automated tools. [...]

CP Violation and New Physics in $B_s$ Decays / Fleischer, Robert (CERN)
The $B_s$-meson system is a key element in the $B$-physics programme of hadron colliders, offering various avenues to explore CP violation and to search for new physics. One of the most prominent decays is $B_s\to J/\psi\phi$, the counterpart of $B_d\to J/\psi K_S$, providing a powerful tool to search for new-physics contributions to $B^0_s$--$\bar{B^0_s}$ mixing.

In Pursuit of New Physics in the B System / Fleischer, Robert (CERN)
The B-meson system offers interesting probes for the search of physics beyond the Standard Model. After addressing possible signals of new-physics contributions to the B -> phi K and B -> pi K decay amplitudes, we focus on the data for B^0_q-\bar B^0_q mixing (q = d, s), giving a critical discussion of their interpretation in terms of model-independent new-physics parameters.

Flavour Physics and CP Violation : Expecting the LHC / Fleischer, Robert (CERN)
The starting point of these lectures is an introduction to the weak interactions of quarks and the Standard-Model description of CP violation, where the central role is played by the Cabibbo-Kobayashi-Maskawa matrix and the corresponding unitarity triangles. Since the B-meson system governs the stage of (quark) flavour physics and CP violation, it is our main focus: we shall classify B-meson decays, introduce the theoretical tools to deal with them, investigate the requirements for non-vanishing CP-violating asymmetries, and discuss the main strategies to explore CP violation and the preferred avenues for physics beyond the Standard Model to enter.
