Relativistic Heavy Quarks on the Lattice [PDF]
, 2001 Lattice QCD should allow quantitative predictions for the heavy quark physics from first principles. Up to now, however, most approaches have based on the nonrelativistic effective theory, with which the continuum limit can not be taken in principle.

Quantum‐Classical Simulation of Quantum Field Theory by Quantum Circuit Learning
Annalen der Physik, Volume 537, Issue 6, June 2025.Quantum circuit learning is employed to simulate quantum field theories (QFTs). By integrating a minimal qubit configuration and low‐depth circuits, the approach predicts real‐time dynamics accurately. It effectively simulates complex phenomena such as quench and chiral dynamics in a model of quantum electrodynamics, aligning well with classical ...

On the power divergence in quasi gluon distribution function
Journal of High Energy Physics, 2018 Recent perturbative calculation of quasi gluon distribution function at one-loop level shows the existence of extra linear ultraviolet divergences in the cut-off scheme.

Simulation of a Three‐Nucleons System Transition on Quantum Circuits
Advanced Quantum Technologies, Volume 8, Issue 5, May 2025.A general procedure is presented to calculate the transition probability for two nuclear states and a transition operator. The ground state is approximated through the variational quantum eigensolver and the first excited one using more sophisticated variational algorithms.

Chiralspin symmetry and confinement
SciPost Physics Proceedings, 2022 Interesting lattice QCD simulations at high temperature in QCD and particular truncated studies have shown the emergence of an unexpected group symmetry, so called \textit{chiralspin}.

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 ...

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.
