Sparticle Mass Hierarchies, Simplified Models from SUGRA Unification, and Benchmarks for LHC Run-II SUSY Searches

David Francescone, Sujeet Akula, Baris Altunkaynak +1

Sparticle mass hierarchies contain significant information regarding the origin and nature of supersymmetry breaking. The hierarchical patterns are severely constrained by electrow…

String Resonances at Hadron Colliders

Luis A. Anchordoqui, Ignatios Antoniadis, De-Chang Dai +6

[Abridged] We consider extensions of the standard model based on open strings ending on D-branes. Assuming that the fundamental string mass scale M_s is in the TeV range and that t…

3.5 keV Galactic Emission Line as a Signal from the Hidden Sector

Ning Chen, Zuowei Liu, Pran Nath

An emission line with energy of keV has been observed in galaxy clusters by two experiments. The emission line is consistent with the decay of a dark matter particle wi…

Electron EDM as a Sensitive Probe of PeV Scale Physics

Tarek Ibrahim, Ahmad Itani, Pran Nath

We give a quantitative analysis of the electric dipole moments as a probe of high scale physics. We focus on the electric dipole moment of the electron since the limit on it is the…

The Physics Programme Of The MoEDAL Experiment At The LHC

B. Acharya, J. Alexandre, J. Bernabéu +59

The MoEDAL experiment at Point 8 of the LHC ring is the seventh and newest LHC experiment. It is dedicated to the search for highly ionizing particle avatars of physics beyond the…

Reconciling BICEP2 and Planck results with right-handed Dirac neutrinos in the fundamental representation of grand unified E_6

Luis A. Anchordoqui, Haim Goldberg, Xing Huang +1

The tensor-to-scalar ratio (r = 0.20^{+0.07}_{-0.05}) inferred from the excess B-mode power observed by the Background Imaging of Cosmic Extragalactic Polarization (BICEP2) experim…
