Near-threshold molecular-like state may appear as threshold cusp especially when the interaction is not strong enough so that a virtual state is formed instead of a bound state. In this talk, I will report experimental identification of a threshold cusp at Belle and some other related results. I will also discuss future plans and possibilities at Belle II and J-PARC.
In this talk, I will be presenting the most recent published work, emphasizing more on the nuclear aspect. Then, I will shift my focus to some points that I realize from this work and some of my past works. The main points will be twofold. First, according to the works that I had done so far, nuclear matter models give a significant shift to the maximum mass of compact stars. Second, although...
Proper determination of pairing residual interaction strengths is crucial in any microscopic mean-field approaches. This has been traditionally performed by fitting the pairing strengths such that the experimental moment of inertia or the odd-even mass differences is reproduced. The equivalence of the two methods in the case of a constant matrix element has been investigated for nuclei in the...
This study calculates the energy decay rates ($r$) for both up and down quarks and the electric form factors ($G_E$) of the proton using low four-momentum transfer ($Q^2$) data from the PRad and MaMi electron-proton scattering experiments. The extracted decay rates for u and d quarks were nearly identical with $rโ3.94$, demonstrating a consistent exponential decay behavior across increasing...
In the present work, we discuss about the internal structure of the electron. The physical electron is considered as a composite system of a bare electron and photon. We mainly discuss about the Wigner distributions, gravitational form factors and mechanical properties of the electron. Results are obtained from the overlap of light-front wave functions in light-front QED model.
As a pseudo-Nambu-Goldstone boson, the kaon provides insights into how explicit chiral symmetry breaking influences the quark structure inside hadrons. In this talk, we explore the properties of the generalized quark distributions of the kaon within the nonlocal chiral quark model. We discuss how the explicit chiral symmetry breaking affects the (generalized) light and strange quark...
We explore the interplay among entanglement suppression, quantum statistics and enhanced symmetries in the non-relativistic S-wave scattering involving the lowest-lying spin-3/2 baryons, which can be considered as four-dimensional qudits. These baryons form a ten-dimensional representation (decuplet) under the SU(3) light-flavor symmetry and, in this limit, are considered indistinguishable...
The production of the excited states of the $\Xi^{-}$ hyperon from proton-kaon collision, $p + K^- \to \Xi^{*-} + K^+$, with the s- and u-channel processes has been studied. We employed the effective Lagrangian method to describe the production of $\Xi^{*-}$ and utilized the Regge model for the u-channel process. To determine the couplings and the form factors for $\Xi^{*-}$, we also carry out...
In relativistic heavy ion collisions, the so-called little bang by analogy with the big bang in early universe can be realized in laboratories, where a deconfined phase of the quantum chromodynamic (QCD) matter at high temperature known as the quark gluon plasma (QGP) is produced. The QGP behaves as a nearly perfect fluid with the anisotropic flow that can be macroscopically described by...
We present a novel unified approach to describe the dense symmetric nuclear matter by combining the quarkyonic matter framework with the parity doublet model. This integration allows for a consistent treatment of
the transition from hadronic to quark degrees of freedom while incorporating chiral symmetry restoration effects. Our model introduces a chiral invariant mass for both baryons and...
Intense electromagnetic fields are formed in high-energy heavy ion collisions by the positively charged colliding ions. According to phenomenological models, charged observables produced in the collisions are affected by those electromagnetic fields [1]. However, the initial stages of the fields are not yet understood. We will discuss how the uncertainties in Glauber modeling of the colliding...
Two-color QCD is one of the useful testing grounds to explore cold and dense QCD medium, since the first-principles lattice numerical simulations are doable without suffering from the so-called sign problem. In this talk, I review recent progress of such numerical experiments. Then, I summarize what is unveiled by comparing with my effective model, the linear sigma model. Also I discuss...
I will review the state-of-the-art high-precision theoretical predictions, which are mandatory components in interpreting the increasingly accurate LHC datasets. I will discuss recent developments in the aspects of higher-order calculations, mainly focusing on the scattering amplitude computation. I will showcase some of the recent high-precision phenomenological studies involving 2->3...
The spectra of stable particles such as photons, positrons,
antiprotons and neutrinos are one of the main ingredients to calculate
the fluxes of cosmic rays and radiation searched for in indirect
detection experiments. The modeling of the whole process is however
very complicated since after dark matter annihilation or decay, a
number of phenomena occur including resonance decays,...
Big Bang Nucleosynthesis (BBN) represents a crucial phase in the universe's evolution, occurring approximately one second after the Big Bang. The BBN theory predicts a primordial Helium-4 abundance of about 25%, offering key limits on the number of light particles present at BBN temperatures. The Left-Right Symmetry Model with an Extra Scalar Field is a development of the Standard Model with...
In this work, we study the vacuum structure of an extended standard model with \$U(1)\_D\$ symmetry. The potential of the proposed model contains two \$SU(2)\$ scalar doublets and two scalar singlets. We theoretically analyze constraints, such as bounded-from-below, global minimum, and perturbativity up to the Planck scale. The experimental bounds from the Higgs invisible decay are also investigated.
