θ dependence of SU (N) gauge theories in the presence of a topological term

E Vicari, H Panagopoulos - Physics Reports, 2009 - Elsevier
We review results concerning the θ dependence of 4D SU (N) gauge theories and QCD,
where θ is the coefficient of the CP-violating topological term in the Lagrangian. In particular …

Sphaleron Rate of QCD

C Bonanno, F D'angelo, M D'elia, L Maio, M Naviglio - Physical Review Letters, 2024 - APS
We compute the sphaleron rate of N f= 2+ 1 QCD at the physical point for a range of
temperatures 200 MeV≲ T≲ 600 MeV. We adopt a strategy recently applied in the quenched …

Accelerating dynamical-fermion computations using the rational hybrid Monte Carlo algorithm with multiple pseudofermion fields

MA Clark, AD Kennedy - Physical review letters, 2007 - APS
There has been much recent progress in the understanding and reduction of the
computational cost of the hybrid Monte Carlo algorithm for lattice QCD as the quark mass …

[图书][B] Multivalued fields: in condensed matter, electromagnetism, and gravitation

H Kleinert - 2008 - books.google.com

Comparison of the gradient flow with cooling in pure gauge theory

C Bonati, M D'Elia - Physical Review D, 2014 - APS
The gradient (Wilson) flow has been introduced recently in order to provide a solid
theoretical framework for the smoothing of ultraviolet noise in lattice gauge configurations. It …

Evidence for the role of instantons in hadron structure from lattice QCD

MC Chu, JM Grandy, S Huang, JW Negele - Physical Review D, 1994 - APS
Cooling is used as a filter on a set of gluon fields sampling the Wilson action to selectively
remove essentially all fluctuations of the gluon field except for the instantons. The close …
