A Thermodynamic Positivity Bound on Higher-Derivative 3-Form Couplings in de Sitter, and its Inflationary Consequences
Nutthaphat Lunrasri, Chakrit Pongkitivanichkul
The paper derives thermodynamic positivity bounds on higher‑derivative couplings of a 3‑form gauge field in de Sitter space using black‑hole mass limits and Wald entropy positivity…
Effect of Cosmic Neutrino Background on the Dark Matter Self-interaction via Neutrino force
Pawin Ittisamai, Chakrit Pongkitivanichkul, Muhammaddaniya Sutwilai +2
Neutrino-pair exchange induces a neutrino force that can drive dark matter (DM) self-interactions and impact small-scale structure formation. In the presence of the cosmic neutrino…
Odderon Form Factors in Reggeized Spin-2 Pomeron and Spin-3 Odderon Exchange in and Elastic Scattering
Dominador F. Vaso, Prin Sawasdipol, Jingle B. Magallanes +2
We investigate the form-factor dependence of Reggeized tensor Pomeron and Odderon exchanges in high-energy elastic and scattering. The spin structure is implemented…
Constraining Axion-Like Particle mediated Dark Matter with Observational Constraints: A Statistical and Machine Learning Approach
Prashant Thakur, Aravind Taridalu, Ishfaq Ahmad Rather +2
We present a comprehensive study of axion-like particle (ALP) mediated dark matter (DM) effects on neutron star (NS) structure within a relativistic mean-field framework with non-l…
Axion-Like Particle Mediated Dark Matter and Neutron Star Properties in the QHD Model
Tanech Klangburam, Chakrit Pongkitivanichkul
We investigate the effects of the ALP-mediated dark matter (DM) model on neutron star properties using the Quantum Hadrodynamics model (QHD). Using the relativistic mean-field appr…
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…
