F-Term Hybrid Inflation with T-Model Kähler Geometry and Beyond
Waqas Ahmed, Constantinos Pallis, Mansoor Ur Rehman
We analyze F-term hybrid inflation (FHI) within various grand unified theories (GUTs) in the presence of a Kähler potential for the inflaton field which parameterizes the Kähler ma…
From N- to (p,N)- Inflationary Attractors in view of ACT
C. Pallis
We review two types of fractional Kaehler potentials which reduce, along the inflationary path, to the form with or and $0.1\leq p\l…
Induced-Gravity Palatini-Like Higgs Inflation in Supergravity Confronts ACT DR6
C. Pallis
We formulate within Supergravity a model of induced-gravity inflation, excellently consistent with ACT DR6, inspired by the Palatini gravity. The inflaton belongs in the decomposit…
GUT-Scale Smooth Hybrid Inflation with a Stabilized Modulus in Light of ACT and SPT Data
Waqas Ahmed, Constantinos Pallis, Mansoor Ur Rehman
We analyze a generalized framework of smooth F-term hybrid inflation (smFHI) consistent with gauge coupling unification within the Minimal Supersymmetric Standard Model (MSSM). The…
Updating GUT-Scale Pole Higgs Inflation After ACT DR6
C. Pallis
We consider models of chaotic inflation driven by the real parts of a conjugate pair of Higgs superfields involved in the spontaneous breaking of a grand unification symmetry at a…
ACT-Inspired Kaehler-Based Inflationary Attractors
C. Pallis
We develop a new class of cosmological attractors which are compatible with the recent ACT results. They are based on two types of fractional Kaehler potentials, K, for a gauge-sin…
Kinetically Modified Palatini Inflation Meets ACT Data
C. Pallis
We show that the coexistence of a non-minimal coupling to gravity with a kinetic mixing of the form -- where $…
Induced-Gravity Inflation in Supergravity Confronted with Planck 2015 & BICEP2/Keck Array
C. Pallis
Supersymmetric versions of induced-gravity inflation are formulated within Supergravity (SUGRA) employing two gauge singlet chiral superfields. The proposed superpotential is uniqu…
Models of Non-Minimal Chaotic Inflation in Supergravity
C. Pallis
We show how we can implement chaotic inflation in the context of supergravity by conveniently selecting the functional form of a strong enough non-minimal coupling between the infl…
