Mean field approximation for effective theories of lattice QCD

Proceedings of The 39th International Symposium on Lattice Field Theory — PoS(LATTICE2022), 2023
For the exploration of the phase diagram of QCD, effective Polyakov loop theories derived from lattice QCD provide a valuable tool in the heavy quark mass regime. In practice, the evaluation of these theories is complicated by the appearance of long-range and multipoint interaction terms.

The Curious Concept That Almost Nobody Seemed to Care About at First: Virtual Particles in the Post-War Period. [PDF]

Ber Wiss
Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

Effective field theory for the crystalline colour superconductive phase of QCD [PDF]

Physics Letters B, 2001
We present an effective field theory for high density, low temperature QCD in the crystalline colour superconductive phase (LOFF phase). This interesting phase of QCD is characterized by a gap parameter with a crystalline pattern, breaking traslational and rotational invariance, and could have astrophysical applications.

An effective field theory calculation of the QCD corrections to weak parameters [PDF]

Nuclear Physics B, 1991
In the standard model the parameters {rho} and M{sub W}{sup 2}/M{sub Z}{sup 2}cos{sup 2}{theta} are unity at tree level. They are protected against large corrections by the so-called custodial symmetry. We investigate the symmetry breaking effect of effect of mass splittings in fermion doublets.

Chiral Fermions on the Lattice [PDF]

, 1998
A recently proposed method for regularizing chiral gauge theories non-perturbatively is discussed in detail. The result is an effective action which can be computed from the lattice gauge field, and which is suited for numerical simulations.Comment: Talk
