Resonant scattering and recombination of pseudo-degenerate WIMPs
Speaker(s): Adam Ritz
Abstract: WIMP dark matter candidates chi^0 have interesting signatures for direct and indirect detection in regimes where there is a near degeneracy with a heavier charged state chi^{pm}, as occurs for example along the boundary of the coannihilation strip in the CMSSM. For small splittings of O(10) MeV, the... read more

Backreaction in Closed String Tachyon Condensation
Speaker(s): Andrew Frey
Abstract: Working in the weak tachyon region of a condensing tachyon background, we find the modified equations of motion for massless strings with conformal perturbation theory. We then estimate the backreaction on the background dilaton. In large (supercritical) dimensions, we find that the backreaction can... read more

Conformal Gravity Challenges String Theory
Speaker(s): Philip Mannheim
Abstract: The cosmological constant problem and the compatibility of gravity with quantum mechanics are the two most pressing problems in all of gravitational theory. While string theory nicely addresses the latter, it has so far failed to provide any compelling solution to the former. On the other hand, whil... read more

Inflation scenario via the Standard Model Higgs boson and LHC
Speaker(s): Andrei Barvinski
Abstract: We discuss a quantum corrected inflation scenario driven by a generic GUT or Standard Model type particle model, whose scalar field playing the role of an inflaton has a strong non-minimal curvature coupling. We show that currently widely accepted bounds on the Higgs mass falsify the suggestion of [... read more

Irreducible flavour and CP violation in SUGRA flavour models
Speaker(s): Michal Malinsky
Abstract: In SUGRA flavour models, a total sequestering is not possible and an irreducible amount of flavour and CP violation is essentially unavoidable, which renders many flavour models testable in the near future experiments.

Monodromy in the CMB: Gravity Waves and String Inflation
Speaker(s): Alexander Westphal
Abstract: We present a simple mechanism for obtaining large-field inflation, and hence a gravitational wave signature, from string theory compactified on twisted tori. For Nil manifolds, we obtain a leading inflationary potential proportional to phi^(2/3) in terms of the canonically normalized field phi, yiel... read more

Neutrino sector impacts SUSY dark matter
Speaker(s): Azar Mustafayev
Abstract: We study effects of the neutrino yukawa coupling on neutralino dark matter observables. We found that presence of the top-like neutrino yukawa coupling does significantly affect neutralino relic density in the regions.

A Born-Infeld action for dark matter and dark energy
Speaker(s): Maximo Banados
Abstract: We consider a Born-Infeld like action for gravity coupled to an external connection field. We show that the equation of state of this fluid interpolates between dark matter and dark energy. We also show that on galactic scales this system predicts asymptotically flat rotation curves. This action is... read more

LHC Signals of MSSM Electroweak Baryogenesis
Speaker(s): David Morrissey
Abstract: The Standard Model (SM) of particle physics provides an excellent description of nearly every collider physics experiment performed to date. However, the SM is unable to explain the observed cosmology. Among its cosmological shortcomings, the SM cannot account for the dark matter or explain why ther... read more
