Quantum chromodynamics with advanced computing [PDF]

, 2008
We survey results in lattice quantum chromodynamics from groups in the USQCD Collaboration. The main focus is on physics, but many aspects of the discussion are aimed at an audience of computational physicists.Comment: 17 pp.

Multiparticle production and quantum chromodynamics [PDF]

, 2002
The theory of strong interactions, quantum chromodynamics (QCD), is quite successful in the prediction and description of main features of multiparticle production processes at high energies.

Quantum Chromodynamics with Many Flavors [PDF]

, 1998
We investigate the phase structure of lattice QCD for general number of flavors $N_F$. Based on numerical data combined with the results of the perturbation theory we propose the following picture: When $N_F \ge 17$, there is only one IR fixed point at ...

Persistent Challenges of Quantum Chromodynamics [PDF]

, 2006
Unlike some models whose relevance to Nature is still a big question mark, Quantum Chromodynamics will stay with us forever. Quantum Chromodynamics (QCD), born in 1973, is a very rich theory supposed to describe the widest range of strong interaction ...

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.

Investigation of the internal structure of the deuteron against the background of two-photon exchange effects in elastic electron-deuteron scattering [PDF]

Ядерна фізика та енергетика
This work aims to investigate the simultaneous influence of two-photon effects in quantum electrodynamics and logarithmic corrections in quantum chromodynamics on certain observable experimental quantities (structure functions A(Q2) and B(Q2) in elastic ...

The Three Loop Two-Mass Contribution to the Gluon Vacuum Polarization [PDF]

, 2017
We calculate the two-mass contribution to the 3-loop vacuum polarization of the gluon in Quantum Chromodynamics at virtuality $p^2 = 0$ for general masses and also present the analogous result for the photon in Quantum Electrodynamics.Comment: 5 pages ...
