Chiral transition in a Non-Abelian Quasi-Particle Model with three quark flavours
Eleftherios P. Politis, Antonis Tsapalis, Fotios K. Diakonos
We combine the recently introduced Non-Abelian Quasi-Particle Model (NAQPM) for gluons with an ideal Fermi gas of three quark species with the aim to describe the equation of state…
Gauss' Law and Non-Linear Plane Waves for Yang-Mills Theory
A. Tsapalis, E. P. Politis, X. N. Maintas +1
We investigate Non-Linear Plane-Wave solutions of the classical Minkowskian Yang-Mills (YM) equations of motion. By imposing a suitable ansatz which solves Gauss' law for the $SU(3…
Oscillons and oscillating kinks in the Abelian-Higgs model
C. E. Tsagkarakis, V. Achilleos, F. K. Diakonos +5
We study the classical dynamics of the Abelian Higgs model employing an asymptotic multiscale expansion method, which uses the ratio of the Higgs to the gauge field amplitudes as a…
A non-abelian quasi-particle model for gluon plasma
E. P. Politis, C. E. Tsagkarakis, F. K. Diakonos +2
We propose a quasi-particle model for the thermodynamic description of the gluon plasma which takes into account non-abelian characteristics of the gluonic field. This is accomplis…
Oscillons and oscillating kinks in the Abelian-Higgs model
V. Achilleos, F. K. Diakonos, D. J. Frantzeskakis +5
We study the classical dynamics of the Abelian Higgs model employing an asymptotic multiscale expansion method, which uses the ratio of the Higgs to the gauge field amplitudes as a…
Determination of Delta resonance parameters from lattice QCD
C. Alexandrou, J. W. Negele, M. Petschlies +2
A method suitable for extracting resonance parameters of unstable baryons in lattice QCD is examined. The method is applied to the strong decay of the Delta to a pion-nucleon state…
