Francesca Curciarello04/08/2016, 17:20Dark Matter DetectionOral PresentationDuring the last years several Dark Sector Models have been proposed in order to address striking astrophysical observations which fail standard intepretations. In the minimal case a new vector particle, the so called dark photon or U-boson, is introduced, with small coupling with Standard Model particles. Also, the existence of a dark Higgs boson h' is postulated, in analogy with the Standard...Go to contribution page

Mauro Raggi (LNF INFN), Paolo Valente (Universita e INFN, Roma I (IT))04/08/2016, 18:00Dark Matter DetectionOral PresentationThe long standing problem of reconciling the cosmological evidence of the existence of dark matter with the lack of any clear experimental observation of it, has recently revived the idea that the new particles are not directly connected with the Standard Model gauge fields, but only through mediator fields or โportalsโ, connecting our world with new โsecludedโ or โhiddenโ sectors. One of the...Go to contribution page

Dr Carol Scarlett (Florida A&M University)04/08/2016, 18:20Dark Matter DetectionOral PresentationABSTRACT: The search for Axions, a particle theorized to explain the lack of CP violation in strong physics and suspected to contribute if not explain galactic dark matter, has lead to ever-sensitive techniques to study induced vacuum birefringence. What remains an issue: many of the measurable parameters that could give evidence for this illusive particle scale with the square of the...Go to contribution page

Enrico Rinaldi (Lawrence Livermore National Laboratory)05/08/2016, 09:20Dark Matter DetectionOral PresentationModels of composite dark matter, originating from a new strongly coupled dark sector, have a very interesting phenomenology. To make robust predictions in these models one often need to investigate non-perturbative effects due to the strong self interactions. Lattice field theory methods and numerical simulations are well suited for this task and contribute to a solid uncertainty...Go to contribution page

Evan Johnson (The Ohio State University)05/08/2016, 10:10Dark Matter DetectionOral PresentationThe first so-called โSommerfeld enhancementโ of neutral wino dark matter annihilation occurs when the wino mass is tuned so there is a charged wino pair bound state at the neutral wino pair threshold. For larger wino mass, the charged wino pair bound state can be formed by a radiative transition in which a pair of photons is emitted. The bound state production rate is calculated in an...Go to contribution page
