The QCD Scale Parameter from the Photon Structure Function

Hun Jang, Eun Bok, Hyeunwoo Kim +2

Photon structure function has been a solid platform in testing strong interaction along with nucleon structure function. Strong Interaction has the property that it is perturbative…

Addressing the sign-problem in Euclidean path integrals with radial basis function neural networks

Gabor Balassa

Solving interacting field theories at finite densities remains a numerically and conceptually challenging task, even with modern computational capabilities. In this paper, we propo…

Finite-temperature stability from doublet inflation field with right-handed neutrinos

Seong Chan Park, Shilpa Jangid

We study the augmentation of the Standard Model (SM) with another Higgs doublet and right-handed neutrinos. The second Higgs doublet () is defined to be odd under the…

Neural network expansion of Euclidean path integrals and its application to interacting scalar fields

Gabor Balassa

Studying phase transitions in interacting quantum field theories generally requires the numerical study of the dynamical system on a large lattice, which is, in most cases, computa…

Beyond the Starobinsky model after ACT

Min Gi Park, Dhong Yeon Cheong, Seong Chan Park

We revisit higher order corrections to the Starobinsky inflationary model using the most recent P-ACT-LB-BK18 data, which exhibits a mild but definite tension with the predictions…

Studying the in-medium meson spectrum through kaons in proton-nucleus reactions

Gabor Balassa, Kazuya Aoki, Philipp Gubler +3

Exploring the mass modifications of mesons in nuclei provides insights into the nature of strongly interacting matter. Specifically, meson mass shifts can be related to the…

Decay and lifetime of oscillons coupled to an external scalar field: Insights from instability band analysis

Siyao Li, Masahide Yamaguchi, Ying-li Zhang

Oscillons are long-lived, spherically symmetric solitons that can arise in real scalar field theories with potentials shallower than quadratic ones. They are considered to form via…

Gravitational Wave Signals in a Promising Realization of SO(10) Unification

Injun Jeong, Jörn Kersten, Stefano Scopel +1

We investigate gravitational wave signals in a non-supersymmetric grand unified model where the group is broken in two steps to the Standard Model gauge group. We calculat…

Strongly electroweak phase transition with gauged non-zero hypercharge triplet

Shilpa Jangid, Anirban Biswas, Seong Chan Park

This article considers three non-zero hypercharge triplets as an extension of the Standard Model Higgs doublet. Under extra symmetry, the triplets are charged. We…

Investigating two-zero texture in the light of gauged Type-II seesaw

Anirban Biswas, Shilpa Jangid, Seong Chan Park

Neutrino oscillation, discovered over two decades ago, confirmed that neutrinos have nonzero masses. Since then, two mass-squared differences have been measured with unprecedented…

Complex heavy-quarkonium potential in an anisotropic collisional quark-gluon plasma

Manas Debnath, Lata Thakur, Najmul Haque

We compute the complex heavy-quark potential in an anisotropic quark-gluon plasma (QGP) using kinetic theory with a Bhatnagar-Gross-Krook collision kernel. By incorporating momentu…

Superheavy Supersymmetric Dark Matter for the origin of KM3NeT Ultra-High Energy signal

Yongsoo Jho, Seong Chan Park, Chang Sub Shin

We propose an explanation for the recently reported ultra-high-energy neutrino signal at KM3NeT, which shows no clear association with known astrophysical sources. While decaying d…

Heavy quark suppression and anisotropic flow at intermediate momentum

Juhee Hong

In an intermediate-momentum regime where mass effects are significant, heavy quark suppression and anisotropic flow are computed to investigate the transition between the collision…
