Analytic continuation in two-color QCD: new results on the critical line
P. Cea, L. Cosmai, M. D'Elia +1
We test the method of analytic continuation from imaginary to real chemical potential in two-color QCD, which is free from the sign problem. In particular, we consider the analytic…
NLO BFKL in gamma* gamma* collisions
F. Caporale, D. Yu. Ivanov, A. Papa
We study in the BFKL approach the total hadronic cross section for the collision of two virtual photons for energies in the range of LEP2 and of future linear colliders. The BFKL r…
Numerical Evidence for the Haldane Conjecture
B. Alles, A. Papa
The Haldane conjecture, when applied to the Heisenberg O(3) model with a θterm in two dimensions, states that the correlation length ξdiverges when θapproaches π. To verify this co…
Non-compact QED3 at finite temperature: the confinement-deconfinement transition
Roberto Fiore, Pietro Giudice, Alessandro Papa
The confinement-deconfinement phase transition is explored by lattice numerical simulations in non-compact (2+1)-dimensional quantum electrodynamics with massive fermions at finite…
Collinear improvement of the BFKL kernel in the electroproduction of two light vector mesons
Francesco Caporale, Alessandro Papa, Agustin Sabio Vera
We test the performance of a RG-improved kernel in the determination of the amplitude of a physical process, the electroproduction of two light vector mesons,in the BFKL approach a…
The critical line from imaginary to real baryonic chemical potentials in two-color QCD
Paolo Cea, Leonardo Cosmai, Massimo D'Elia +1
The method of analytic continuation from imaginary to real chemical potentials is one of the few available techniques to study QCD at finite temperature and baryon density. One…
