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 ...

Recent progress in computing four-loop massive correlators [PDF]

, 2006
We report about recent progress in computing four-loop massive correlators. The expansion of these correlators in the external momentum leads to vacuum integrals.

Three Dimensional Quantum Chromodynamics [PDF]

, 1992
The subject of this talk was the review of our study of three ($2+1$) dimensional Quantum Chromodynamics. In our previous works, we showed the existence of a phase where parity is unbroken and the flavor group $U(2n)$ is broken to a subgroup $U(n)\times ...

New Approach to Investigation of Nuclei

EPJ Web of Conferences, 2014
We demonstrate that the sum rules of quantum chromodynamics provide a consistent formalism for solving various problems of nuclear physics.

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 ...

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.

The Critical End Point of Quantum Chromodynamics Detected by Chirally Imbalanced Quark Matter

, 2011
We suggest the idea, supported by concrete calculations within chiral models, that the critical endpoint of the phase diagram of Quantum Chromodynamics with three colors can be detected, by means of Lattice simulations of grand-canonical ensembles with a
