Polarization rotation of chiral fermions in vortical fluid
Physics Letters B, 2021 The rotation of polarization occurs for light interacting with chiral materials. It requires the light states with opposite chiralities interact differently with the materials.

The Georgi "Avatar" of Broken Chiral Symmetry in Quantum Chromodynamics [PDF]
arXiv, 1999 We establish that in Quantum Chromodynamics (QCD) at zero temperature, SU_{L+R}(N_F) exhibits the vector mode conjectured by Georgi and SU_{L-R}(N_F) is realized in either the Nambu-Goldstone mode or else Q_5^a is also screened from view at infinity. The Wigner-Weyl mode is ruled out unless the beta function in QCD develops an infrared stable zero.

Chromoelectric flux tubes within non-Abelian Proca theory
European Physical Journal C: Particles and FieldsFlux tube solutions within non-Abelian SU(3) Proca theory with external sources are obtained. It is shown that such tubes have a longitudinal chromoelectric field possessing two components (nonlinear and gradient), as well as a transverse chromomagnetic ...

On the number of colours in Quantum Chromodynamics [PDF]
arXiv, 2000 It is commonly believed that ${\pi}^0 \to 2 \gamma$ decay shows that there are three colours in Quantum Chromodynamics (QCD). It is shown here that this is not correct. When correct colour dependent charges of the quarks are considered then it is shown that this decay does not make any statement about the number of colours in QCD.

CONSTRAINING NEUTRON STAR MATTER WITH QUANTUM CHROMODYNAMICS
, 2014 In recent years, there have been several successful attempts to constrain the equation of state of neutron star matter using input from low-energy nuclear physics and observational data.

PERSISTENT CHALLENGES OF QUANTUM CHROMODYNAMICS [PDF]
International Journal of Modern Physics A, 2006 Unlike some models whose relevance to Nature is still a big question mark, Quantum Chromodynamics (QCD) will stay with us forever. QCD, born in 1973, is a very rich theory supposed to describe the widest range of strong interaction phenomena: from nuclear physics to Regge behavior at large E, from color confinement to quark–gluon matter at high ...

Quantum electrodynamics in finite volume and nonrelativistic effective field theories
Physics Letters B, 2016 Electromagnetic effects are increasingly being accounted for in lattice quantum chromodynamics computations. Because of their long-range nature, they lead to large finite-size effects over which it is important to gain analytical control. Nonrelativistic

Theoretical Errors in Contemporary Physics [PDF]
arXiv, 2005 Errors pertaining to the following physical theories are discussed: the Dirac magnetic monopole theory; the Klein-Gordon equation; the Yukawa theory of nuclear force; the idea of Vector Meson Dominance; the Aharonov-Bohm effects; the idea of diffraction-free electromagnetic beams; Quantum Chromodynamics.

Testing Quantum Chromodynamics with Antiprotons [PDF]
, 2004 The antiproton storage ring HESR to be constructed at GSI will open up a new range of perturbative and nonperturbative tests of QCD in exclusive and inclusive reactions. I discuss 21 tests of QCD using antiproton beams which can illuminate novel features of QCD.
