U(1) Problem at Finite Temperature
Romuald A. Janik, Maciej A. Nowak, Gabor Papp +1
We model the effects of a large number of zero and near-zero modes in the QCD partition function by using sparse chiral matrix models with an emphasis on the quenched topological s…
Nuclear Effects in High Energy Photon and Neutral Pion Production
Gabor Papp, George Fai, Peter Levai
We study the mechanism of the and enhancement at large transverse momenta in proton-nucleus collisions. A proposed mechanism suggests an increase in the width of the tran…
Chiral Disorder in Two-Color QCD with Abelian External Fluxes
Romuald A. Janik, Maciej A. Nowak, Gabor Papp +1
We investigate the effects of several Abelian external fluxes , on the Euclidean Dirac spectrum of light quarks in QCD with two colors. Our results provide for a novel way of as…
Green's Functions in Non-hermitian Random Matrix Models
Romuald A. Janik, Maciej A. Nowak, Gabor Papp +1
We review some recent techniques for dealing with non-hermitian random matrix models based on generalized Green's functions. We introduce the diagrammatic methods in the hermitian…
On the Convergence of the Expansion of Renormalization Group Flow Equation
G. Papp, B. -J. Schaefer, H. -J. Pirner +1
We compare and discuss the dependence of a polynomial truncation of the effective potential used to solve exact renormalization group flow equation for a model with fermionic inter…
Renormalization Group Flow Equation at Finite Density
J. Meyer, G. Papp, H. -J. Pirner +1
For the linear sigma model with quarks we derive renormalization group flow equations for finite temperature and finite baryon density using the heat kernel cutoff. At zero tempera…
