PSL(2,7) Representations and their relevance to Neutrino Physics
G. Aliferis, G. K. Leontaris, N. D. Vlachos
The investigation of the role of finite groups in flavor physics and particularly, in the interpretation of the neutrino data has been the subject of intensive research. Motivated…
Non-Minimal Quartic Inflation in Supersymmetric SO(10)
George K. Leontaris, Nobuchika Okada, Qaisar Shafi
We describe how quartic () inflation with non-minimal coupling to gravity is realized in realistic supersymmetric models. In a well-motivated example the $16-\overli…
R-Parity violation in F-Theory
Miguel Crispim Romão, Athanasios Karozas, Stephen F. King +2
We discuss R-parity violation (RPV) in semi-local and local F-theory constructions. We first present a detailed analysis of all possible combinations of RPV operators arising from…
Masses of Third Family Vector-like Quarks and Leptons in Yukawa-Unified
Aditya Hebbar, George K. Leontaris, Qaisar Shafi
In supersymmetric the masses of the third family quarks and charged lepton, , as well as the masses of the vector-like quarks and leptons, and …
Diphoton Resonance in F-theory inspired Flipped SO(10)
George K. Leontaris, Qaisar Shafi
Motivated by the diphoton excess at 750 GeV reported by the ATLAS and CMS experiments, we present an F-theory inspired flipped model embedded in an GUT. The low ener…
750 GeV Diphoton excess from in F-theory GUTs
Athanasios Karozas, Stephen F. King, George K. Leontaris +1
We interpret the 750-760 GeV diphoton resonance as one or more of the spinless components of a singlet superfield arising from the three 27-dimensional representations of in…
