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.

Collins and Sivers asymmetries in muonproduction of pions and kaons off transversely polarised proton / Adolph, C. ; Akhunzyanov, R. ; Alexeev, M.G. ; Alexeev, G.D. ; Amoroso, A. ; Andrieux, V. ; Anosov, V. ; Austregesilo, A. ; Badelek, B. ; Balestra, F. et al. /COMPASS
Measurements of the Collins and Sivers asymmetries for charged pions and charged and neutral kaons produced in semi-inclusive deep-inelastic scattering of high energy muons off transversely polarised protons are presented. The results were obtained using all the available COMPASS proton data, which were taken in the years 2007 and 2010. [...]

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.
