Title: Beyond the CMSSM
Host: Mani Tripathi
Room: 285
Abstract: The apparent discovery of a Higgs boson with mass ∼ 125 GeV has had a significant impact on the constrained minimal supersymmetric extension of the Standard Model in which the scalar masses, gaugino masses and tri-linear A-terms are assumed to be universal at the GUT scale (the CMSSM). Much of the low-mass parameter space in the CMSSM has been excluded by supersymmetric particle searches at the LHC as well as by the Higgs mass measurement and the emergent signal for Bs → μ+μ−. In this talk, I’ll discuss the impact of these recent results on several variants of the CMSSM and related models, focusing on scenarios in which the lightest supersymmetric particle is a viable dark matter candidate

Title: Discrete Wheeler-DeWitt equations in 2 + 1 dimensions
Host: Steve Carlip
Room: 285
Abstract: The infrared structure of quantum gravity is explored by solving a lattice version of the Wheeler-DeWitt equations. For this talk, the case of 2+1 dimensions is presented. The wavefunction solutions only depend on the geometric quantities indicating preservation of diffeomorphism. Properties of the lattice vacuum are consistent with the existence of an ultraviolet fixed point in G located at the origin, thus precluding the existence of a weak coupling perturbative phase. The correlation length exponent is determined exactly and found to be nu=6/11. The results obtained lend support to the claim that the Lorentzian and Euclidean formulations belong to the same field-theoretic universality class.

Title:The Latest on Neutrinos from T2K
Host: Svoboda
Room: 285
Abstract: The Tokai-to-Kamioka (T2K) experiment uses an intense beam of muon neutrinos sent 295 km across Japan to the Super-Kamiokande detector to study fundamental properties of neutrinos, in particular the mixing of neutrino mass and flavor eigenstates which leads to neutrino oscillations. In addition to studying the appearance of electron neutrinos sensitive to the mixing parameter theta13, T2K can make precise measurements of theta23, which governs muon neutrino to tau neutrino conversion. I will report on the latest results from T2K, in particular the recent measurements of theta23 and future prospects for precision measurements of neutrino oscillation parameters
