Quark-hadron phase transition in a magnetic field
N. O. Agasian, S. M. Fedorov
Quark-hadron phase transition in QCD in the presence of magnetic field is studied. It is shown that both the temperature of a phase transition and latent heat decrease compared to…
Debye screening in the hot non-Abelian plasma
N. O. Agasian, Yu. A. Simonov
The Debye mass m_D is computed nonperturbatively in the deconfined phase of QCD, where chromomagnetic confinement is known to be present. The latter defines m_D to be m_D=c_D\sqrt{…
Instanton in the nonperturbative QCD vacuum
N. O. Agasian, S. M. Fedorov
The influence of nonperturbative fields on instantons in quantum chromodynamics is studied. Effective action for instanton is derived in bilocal approximation and it is demonstrate…
Instanton Screening in the Nonperturbative Gluodynamics
N. O. Agasian
The gluon fields screening in the stochastic vacuum of gluodynamics is studied. The effective action is derived for the instanton interacting with nonperturbative fields. Quantum n…
