The Preheating Stage on The Starobinsky Inflation after ACT
Norma Sidik Risdianto, Romy Hanang Setya Budhi, Nehla Shobcha +2
In this paper, we reinvestigate the Starobinsky inflation model and its reheating features in light of the recent ACT results. To make the Starobinsky model consistent with the ACT…
Determination of the HERA coherent diffractive production cross section via artificial neural network
Taufiq Iqbal Baihaqi, Chalis Setyadi, Zulkaida Akbar +2
An exclusive coherent diffractive production dataset from HERA, covering a large kinematic range in the photon virtuality , the squared momentum transfer , and the p…
Thermal Casimir Effect in A Schwarzschild-like Wormhole Spacetime
Arista Romadani, Apriadi Salim Adam, Ar Rohim +2
We study the finite-temperature Casimir effect for a massless scalar field confined between two parallel plates in a Schwarzschild-like wormhole spacetime. Imposing Dirichlet bound…
Fermionic Casimir effect in the presence of compact dimension in field theory with Lorentz invariance violation
Ar Rohim, Apriadi Salim Adam
In this study, we investigate the effect of the Lorentz invariance violation on the Casimir energy and pressure of the massive fermion field in the presence of the compact dimensio…
Spacetime evolution of lepton number densities and wave packet-like effects for neutrino flavor and chiral oscillations in quantum field theory
Apriadi Salim Adam, Nicholas J. Benoit, Yuta Kawamura +4
We present a formulation of lepton family numbers, based on quantum field theory, for neutrino oscillation phenomenology that can be applied to nonrelativistic and relativistic ene…
The Second-Level Preheating
Norma Sidik Risdianto, Apriadi Salim Adam, Lalu Zamakhsyari
This paper proposes two levels of preheating for the inflaton that is non-minimally coupled with gravity. The first level, later named by the quadratic regime, corresponds to the m…
