Aspects Of Phenomenology And Cosmology In Heterotic M-Theory
We present an exploration of models of particle phenomenology and cosmology which arise from the E_8 x E_8 heterotic string theory and its strong-coupled limit, known as heterotic M-theory. We first re-examine the B-L MSSM, a realistic supersymmetric extension of the Standard Model, in a more …

Signals from portals to non-minimal hidden sectors
Hidden Sectors (HS) that exclusively contain particles that are neutral under the Standard Model (SM) gauge groups can address some of the problems of the SM, such as the origin of neutrino masses, the little hierarchy problem, and the nature of dark matter. In these scenarios, interactions of the …

Parton Distributions in Beyond the Standard Model Theories
… the assumption that the Standard Model (SM) of particle physics is complete; however, this can bias studies of beyond the Standard Model (BSM) physics if these SM-like PDFs are used in these analyses. It is important to quantify the extent to which this occurs, in order to avoid making incorrect …

Exploration of models of dark matter and portals to new physics
Although the Standard Model of particle physics has seen tremendous experimental success, there remain still unanswered questions. One such question is the nature of dark matter, which has been only observed through its gravitational effects and yet comprises about 80% of all matter in the …
