 Determination of gamma and -2beta_s from charmless two-body decays of beauty mesons / LHCb collaboration Using the latest LHCb measurements of time-dependent CP violation in the B^0_s -> K^+K^- decay, a U-spin relation between the decay amplitudes of B^0_s -> K^+K^- and B^0 -> \pi^+\pi^- decay processes allows constraints to be placed on the angle gamma of the unitarity triangle and on the B^0_s mixing phase -2\beta_s.

 The NUHM2 after LHC Run 1 / Buchmueller, O ; Cavanaugh, R ; Citron, M ; De Roeck, A ; Dolan, M J ; Ellis, J R ; Flaecher, H ; Heinemeyer, S ; Malik, S ; Marrouche, J et al. We make a frequentist analysis of the parameter space of the NUHM2, in which the soft supersymmetry (SUSY)-breaking contributions to the masses of the two Higgs multiplets, $m^2_{H_{u,d}}$, vary independently from the universal soft SUSY-breaking contributions $m^2_0$ to the masses of squarks and sleptons.
