Removability criterion for radiative corrections to the Starobinsky attractor in weakly nonlocal gravity
Ekapob Kulchoakrungsun, Phongpichit Channuie, Daris Samart
Radiative corrections at the percent level can shift the predictions of -attractor and Starobinsky-like models into the region of the plane preferred by ACT DR6. We sh…
Vector Perturbations in Ghost-Free Quasidilaton Massive Gravity
Ekapob Kulchoakrungsun, Daris Samart
We study transverse vector perturbations in ghost-free extended quasidilaton massive gravity without a quasidilaton kinetic term, in the presence of minimal matter. In vacuum, we r…
Reviving Motivated Inflationary Potentials with -inflation in the light of ACT
Milad Solbi, Daris Samart, Peera Simakachorn
Recent ACT data favor a higher scalar spectral index , placing models such as -attractor T-models and natural Inflation in tension with current observations. We propose a…
The gravitational wave echoes from the black hole with three-form fields
Natthason Autthisin, Supakchai Ponglertsakul, Daris Samart
In this work, we study of massless three-form black hole, where the three-form fields are higher -form gauge fields with . These give rise to the Schwarzschild-de Sitter (S…
Kaluza-Klein inspired a model of the inflation with the inversed power law potential in Bianchi type-I universe
Jaturaporn Wattanakumpolkij, Patinya Ma-ardlerd, Natthason Autthisin +4
This work considers the dynamics of the gauge vector and inflaton (dilaton) fields inspired by Kaluza-Klein theory in an inflationary universe with Bianchi type-I spacetime. The in…
Dark Universe inspired by the Kaluza-Klein gravity and impact on Primordial Gravitational Waves
Kimet Jusufi, Giuseppe Gaetano Luciano, Ahmad Sheykhi +1
We explore the potential implications of Kaluza-Klein (KK) gravity in unifying the dark sector of the Universe. Through dimensional reduction in KK gravity, the 5D spacetime framew…
