Dark Matter
Marco Cirelli, Alessandro Strumia, Jure Zupan
We review observational, experimental and theoretical results related to Dark Matter.
Monodromy Dark Matter
Joerg Jaeckel, Viraf M. Mehta, Lukas T. Witkowski
Light pseudo-Nambu-Goldstone bosons (pNGBs) such as, e.g.~axion-like particles, that are non-thermally produced via the misalignment mechanism are promising dark matter candidates.…
Musings on cosmological relaxation and the hierarchy problem
Joerg Jaeckel, Viraf M. Mehta, Lukas T. Witkowski
Recently Graham, Kaplan and Rajendran [1] proposed cosmological relaxation as a mechanism for generating a hierarchically small Higgs vacuum expectation value. Inspired by this we…
Proton Stability, Gauge Coupling Unification and a Light in Heterotic-string Models
Alon E. Faraggi, Viraf M. Mehta
We explore the phenomenological viability of a light Z' in heterotic-string models, whose existence has been motivated by proton stability arguments. A class of quasi-realistic str…
Leptophobic Z' in Heterotic-String Derived Models
Alon E. Faraggi, Viraf M. Mehta
The CDF collaboration's recent observation of an excess of events in the Wjj channel may be attributed to a new Abelian vector boson with suppressed couplings to leptons. While D0…
Proton Stability and Light Inspired by String Derived Models
Alon E. Faraggi, Viraf M. Mehta
Proton stability is one of the most perplexing puzzles in particle physics. While the renormalizable Standard Model forbids proton decay mediating operators due to accidental globa…
