Multimodal Fragmentation of Hidden‐Heavy Scalar Tetraquarks With HF‐NRevo
Annalen der Physik, Volume 538, Issue 10, October 2026.A state‐driven multimodal framework is introduced for hidden‐heavy scalar tetraquark fragmentation. Distinct microscopic production mechanisms are consistently related to different internal hadronic configurations while theoretical uncertainties are systematically quantified.

QCD Thermodynamics on the Lattice
Advances in High Energy Physics, 2013 A remarkable progress has been made in the understanding of the hot and dense QCD matter using lattice gauge theory. The issues which are very well understood as well as those which require both conceptual and algorithmic advances are highlighted.

Search of QCD phase transition points in the canonical approach of the NJL model
Physics Letters B, 2019 We study the Lee-Yang zeros in the canonical approach to search phase transition points at finite temperature and density in the Nambu-Jona-Lasinio (NJL) model as an effective model of QCD.

Polynomial Preconditioning for Indefinite Matrices
Numerical Linear Algebra with Applications, Volume 33, Issue 5, October 2026.ABSTRACT Polynomial preconditioning is an important tool in solving large linear systems and eigenvalue problems. A polynomial from GMRES can be used to precondition restarted GMRES and restarted Arnoldi. Here we give methods for indefinite matrices that make polynomial preconditioning more generally applicable. The new techniques include balancing the

Generalized Beth–Uhlenbeck Entropy Formula From the Φ‐Derivable Approach
Contributions to Plasma Physics, Volume 66, Issue 7-8, September 2026.ABSTRACT We derive a generalized Beth–Uhlenbeck formula for the entropy of a dense fermion system with strong two‐particle correlations, including scattering states and bound states. We work within the Φ‐derivable approach to the thermodynamic potential.

Twisted mass QCD at finite temperature [PDF]
, 2012 We discuss the use of Wilson fermions with twisted mass for simulations of QCD thermodynamics. As a prerequisite for a future analysis of the finite-temperature transition making use of automatic O(a) improvement, we investigate the phase structure in ...

Results and techniques for higher order calculations within the gradient-flow formalism
Journal of High Energy Physics, 2019 We describe in detail the implementation of a systematic perturbative approach to observables in the QCD gradient-flow formalism. This includes a collection of all relevant Feynman rules of the five-dimensional field theory and the composite operators ...
