Shifted Hybrid Realization of Non-Minimal Higgs Inflation in Light of ACT DR6 and Planck Data
Nadir Ijaz, Pirzada, Mansoor Ur Rehman
We investigate non-minimal Higgs inflation in a no-scale-inspired supergravity framework and confront its predictions with the latest CMB constraints from ACT DR6 and \emph{Planck}…
Revisiting primordial black hole dark matter from axion inflation
Gabriele Franciolini, Nadir Ijaz, Marco Peloso
We revisit the production of primordial black holes (PBHs) by a U(1) gauge field with a pseudo-scalar coupling to the inflaton. We improve upon the existing literature by working i…
Axion inflation in the regime of homogeneous backreaction
Matteo Barbon, Nadir Ijaz, Marco Peloso
We investigate the Stochastic Gravitational Wave Background (SGWB) produced in models of axion inflation coupled to gauge fields. Achieving a detectable signal at Pulsar Timing Arr…
Exploring primordial black holes and gravitational waves with R-symmetric GUT Higgs inflation
Nadir Ijaz, Mansoor Ur Rehman
This study investigates the realization of R-symmetric Higgs inflation within the framework of no-scale-like supergravity, aiming to elucidate the formation of primordial black hol…
New Inflation in Waterfall Region
Niamat Ullah Khan, Nadir Ijaz, Mansoor Ur Rehman
We introduce a class of new inflation models within the waterfall region of a generalized hybrid inflation framework. The initial conditions are generated in the valley of hybrid p…
The Stochastic Gravitational-Wave Background from Primordial Black Holes in R-Symmetric Inflation
Nadir Ijaz, Maria Mehmood, Mansoor Ur Rehman
This study explores the realization of nonminimally coupled Higgs inflation in the context of no-scale supergravity, investigates the formation of primordial black holes, and exami…
