Physics performances for Scalar Electrons, Scalar Muons and Scalar Neutrinos searches at CLIC

The determination of scalar leptons and gauginos masses is an important part of the program of spectroscopic studies of Supersymmetry at a high energy linear collider. In this talk we present results of a study of pair produced Scalar Electrons, Scalar Muons and Scalar Neutrinos searches in a Supersymmetric scenario at 3 TeV at CLIC. We present the performances on the lepton energy resolution and report the expected accuracies on the production cross sections and on the scalar leptons and gauginos masses.

$gamma$ measurements at LHCb

The LHCb collaboration has studied various promising ways to determine the Unitarity Triangle angle $γ$. Three complementary methods will be considered. The potential of the $B \to DK^{(*)}$ decays has been studied by employing the combined Gronau-London-Wyler (GLW) and the Atwood-Dunietz-Soni (ADS) methods, making use of a large sample of simulated data. $γ$ can also be extracted with a time-dependent analysis of $B_s \to D_s K$ decays, provided that the $B_s$ mixing phase is measured independently. In addition, the combined measurement of the $B^0 \to π^+ π^-$ and $B^0_s \to K^+K^-$ time-dependent CP asymmetries allows the determination of $γ$, up to U-spin flavour symmetry breaking corrections. For each method the expected sensitivities to the angle $γ$ are presented.
