Condensation of Lee-Yang zeros in scalar field theory
N. G. Antoniou, F. K. Diakonos, X. N. Maintas +1
We show that, at the critical temperature, there is a class of Lee-Yang zeros of the partition function in a general scalar field theory, which location scales with the size of the…
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…
Symmetric solitonic excitations of the (1+1)-dimensional Abelian-Higgs "classical vacuum"
F. K. Diakonos, G. C. Katsimiga, X. N. Maintas +1
We study the classical dynamics of the Abelian-Higgs model in (1+1) space-time dimensions bf for the case of strongly broken gauge symmetry. In this limit the wells of the potentia…

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…
A multi-scale perturbative approach to SU(2)-Higgs classical dynamics: stability of nonlinear plane waves and bounds of the Higgs field mass
V. Achilleos, F. K. Diakonos, D. J. Frantzeskakis +4
We study the classical dynamics of SU(2)-Higgs field theory using multiple scale perturbation theory. In the spontaneously broken phase, assuming small perturbations of the Higgs f…
Partonic transverse momenta in non-relativistic hyper-central quark potential models
F. K. Diakonos, N. K. Kaplis, X. N. Maintas
We investigate the impact of three-body forces on the transverse-momentum distribution of partons inside the proton. This is achieved by considering the three-body problem in a cla…
MIT bag model inspired partonic transverse momentum distribution for prompt photon production in pp collisions
F. K. Diakonos, N. K. Kaplis, X. N. Maintas
We consider the prompt photon production in pp collisions using, within the framework of perturbative QCD, a non-Gaussian distribution for the transverse momentum distribution of t…
Transverse momentum parton distributions inspired by a quark potential model
F. K. Diakonos, G. D. Galanopoulos, X. N. Maintas
We derive a nonperturbative transverse momentum distribution for partons using a potential model to describe the quark-quark interaction inside the proton. We use this distribution…
Static and non-static quantum effects in two-dimensional dilaton gravity
C. Chiou-Lahanas, G. A. Diamandis, B. C. Georgalas +2
We study backreaction effects in two-dimensional dilaton gravity. The backreaction comes from an term which is a part of the one-loop effective action arising from massive sc…
Time-dependent perturbations in two-dimensional String Black Holes
G. A. Diamandis, B. C. Georgalas, X. Maintas +1
We discuss time-dependent perturbations (induced by matter fields) of a black-hole background in tree-level two-dimensional string theory. We analyse the linearized case and show t…
