Deconfinement in Matrix Models about the Gross--Witten Point
Adrian Dumitru, Jonathan Lenaghan, Robert D. Pisarski
We study the deconfining phase transition in SU(N) gauge theories at nonzero temperature using a matrix model of Polyakov loops. The most general effective action, including all te…
Fluctuation Induced Critical Behavior at Non-Zero Temperature and Chemical Potential
K. Splittorff, J. T. Lenaghan, J. Wirstam
We discuss phase transitions in relativistic systems as a function of both chemical potential and temperature. The presence of a chemical potential explicitly breaks Lorentz invari…
Melting the Diquark Condensate in Two-Color QCD: A Renormalization Group Analysis
J. Wirstam, J. T. Lenaghan, K. Splittorff
We use a Landau theory and the epsilon expansion to study the superfluid phase transition of two-color QCD at nonzero temperature, T, and baryonic chemical potential, mu. At low T,…
Saturation and Pion Production in Proton-Nucleus Collisions
J. T. Lenaghan, K. Tuominen
We study the effects of gluon saturation on pion production in high energy proton-nucleus collisions using the color glass condensate model. At high p_perp, we show that the p_perp…
The -Vacua and the Leutwyler--Smilga Scaling Regime
J. T. Lenaghan
The partition function of QCD is studied in the Leutwyler--Smilga scaling regime for an arbitrary number of quark flavors and masses including the contributions from all winding nu…
