NΩ dibaryon from lattice QCD near the physical point
Physics Letters B, 2019 The nucleon(N)-Omega(Ω) system in the S-wave and spin-2 channel (S25) is studied from the (2+1)-flavor lattice QCD with nearly physical quark masses (mπ≃146MeV and mK≃525MeV).

European Physical Journal C: Particles and Fields, 2020 Double parton distribution functions (dPDFs), entering the double parton scattering (DPS) cross section, are unknown fundamental quantities encoding new interesting properties of hadrons. Here, the pion dPDFs are investigated within different holographic

Exploring Dark Photon Production and Kinetic Mixing Constraints in Heavy‐Ion Collisions
Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.ABSTRACT Vector U‐bosons, often referred to as “dark photons,” are potential candidates for mediating dark matter interactions. In this study, we outline a procedure to derive theoretical constraints on the upper bound of the kinetic mixing parameter ϵ2MU$$ {\upvarepsilon}^2\left({M}_U\right) $$ using dilepton data from heavy‐ion from SIS to RHIC ...

ΛN and Ξ N Interactions Studied with Lattice QCD
EPJ Web of Conferences, 2010 We present our recent studies of Lambda-Nucleon (ΛN) as well as Cascade-Nucleon (ΞN) interactions by using lattice QCD. The equal-time Bethe-Salpeter (BS) amplitude of the lowest energy scattering state of baryon number B = 2 system (proton-Λ and ...

Visible GeV ALP from TeV Vector‐Like Leptons
Fortschritte der Physik, Volume 73, Issue 3, March 2025.Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.

Lattice QCD and Baryon-Baryon Interactions: HAL QCD Method
Frontiers in Physics, 2020 In this article, we review the HAL QCD method to investigate baryon-baryon interactions, such as nuclear forces in lattice QCD. We first explain our strategy in detail to investigate baryon-baryon interactions by defining potentials in field theories ...

Studies of Parity Violation in Atoms
Annalen der Physik, Volume 537, Issue 2, February 2025.This article provides an overview of atomic parity violation (APV), emphasizing its role in testing the Standard Model and probing new physics. The review discusses manifestations of APV, including nuclear‐spin‐independent and dependent effects, and explores isotopic comparison as a method for precision measurements.
