models with a vector-like fermion family
A. Karozas, G. K. Leontaris, I. Tavellaris
Motivated by experimental measurements indicating deviations from the Standard Model predictions we discuss F-theory inspired models, which, in addition to the three chiral generat…
Gravitino Dark matter, Non Thermal Leptogenesis and Low reheating temperature in No-scale Higgs Inflation
Waqas Ahmed, Athanasios Karozas, George K. Leontaris
We revisit Higgs inflation in the framework of a minimal extension of the Standard Model gauge symmetry by a factor. Various aspects are taken into account with partic…
Low Scale String Theory Benchmarks for Hidden Photon Dark Matter Interpretations of the XENON1T Anomaly
Athanasios Karozas, Stephen F. King, George K. Leontaris +1
An excess of low-energy electronic recoil events over known backgrounds was recently observed in the XENON1T detector, where events are observed compared to an expected $232…
On the LHC signatures of F-theory motivated models
A. Karozas, G. K. Leontaris, I. Tavellaris +1
We study low energy implications of F-theory GUT models based on extended by a symmetry which couples non-universally to the three families of quarks and leptons. T…
Inflation from a No-scale supersymmetric model
Waqas Ahmed, Athanasios Karozas
We study inflation in a supersymmetric Pati-Salam model driven by a potential generated in the context of no-scale supergravity. The Pati-Salam gauge group $SU(4)_{c}\times{SU(2)_{…
Vectorlike Particles, and Yukawa Unification in F-theory inspired
Athanasios Karozas, George K. Leontaris, Qaisar Shafi
We explore the low energy implications of an F-theory inspired model whose breaking yields, in addition to the MSSM gauge symmetry, a gauge boson associated with a $U(1)…
