String loop origin for dark radiation and superheavy dark matter in type IIB compactifications
Vasileios Basiouris
In this article we study the significance of string loop corrections, in a perturbative moduli stabilization scenario, focusing on their role in unraveling the origin of dark radia…
Energy-scaling behavior of intrinsic transverse momentum parameters in Drell-Yan simulation
CMS Collaboration
An analysis is presented based on models of the intrinsic transverse momentum (intrinsic ) of partons in nucleons by studying the dilepton transverse momentum in Drel…
Leptogenesis in Realistic Flipped SU(5)
Stephen F. King, George K. Leontaris, Luca Marsili +1
We study thermal leptogenesis in realistic supersymmetric flipped unification. As up-type quarks and neutrinos are arranged in the same multiplets, they exhibit…
Hard processes in multi-TeV ion collisions
Benjamin Fuks, Fotis Marugas, Richard Ruiz +1
Motivated by the ion-collision program at the Large Hadron Collider, plans for its high-luminosity upgrade, and on-going discussions for multi-TeV future hadron colliders, we syste…
Flipped SU(5): unification, proton decay, fermion masses and gravitational waves
Stephen F. King, George K. Leontaris, Ye-Ling Zhou
We study supersymmetric (SUSY) flipped unification, focussing on its predictions for proton decay, fermion masses and gravitational waves. We performed a two-loo…
Computing Tools for Effective Field Theories
Jason Aebischer, Matteo Fael, Javier Fuentes-Martín +30
In recent years, theoretical and phenomenological studies with effective field theories have become a trending and prolific line of research in the field of high-energy physics. In…
SmeftFR v3 -- Feynman rules generator for the Standard Model Effective Field Theory
A. Dedes, J. Rosiek, M. Ryczkowski +2
We present version 3 of SmeftFR, a Mathematica package designed to generate the Feynman rules for the Standard Model Effective Field Theory (SMEFT) including the complete set of ga…
Hybrid Inflation, Reheating and Dark Radiation in a IIB perturbative moduli stabilization scenario
Waqas Ahmed, Athanasios Karozas, George K. Leontaris +1
We study the cosmological implications of an effective field theory model derived within a configuration of D7 brane stacks in the framework of type-IIB string theory. We consider…
Sterile neutrinos, decay and the W-boson mass anomaly in a Flipped from F-theory
Vasileios Basiouris, George K. Leontaris
We investigate the low energy properties of an effective local model with flipped gauge group, constructed within the framework of F-theory. Its origin is trac…
Addendum to "Ultraviolet behaviour of Higgs inflation models"
Ignatios Antoniadis, Anthony Guillen, Kyriakos Tamvakis
This article is an addendum to [1]. We extend our computation of the on-shell scattering amplitudes in an arbitrary inflaton background . Although the effective Einstein f…
Consequences of the Dresden-II reactor data for the weak mixing angle and new physics
D. Aristizabal Sierra, V. De Romeri, D. K. Papoulias
The Dresden-II reactor experiment has recently reported a suggestive evidence for the observation of coherent elastic neutrino-nucleus scattering, using a germanium detector. Given…
