Holographic bottomonium formation in a cooling strong-interaction medium at finite baryon density

Revisiting strong coupling QCD at finite temperature and baryon density

The strong coupling limit (βgauge = 0) of lattice QCD with staggered fermions enjoys the same non-perturbative properties as continuum QCD, namely confinement and chiral symmetry breaking. In contrast to the situation at weak coupling, the sign problem which appears at finite density can be brought under control for a determination of the full (μ ,T ) phase diagram by Monte Carlo simulations. F...

Bottomonium dissociation in a finite density plasma

Nelson R. F. Braga∗ and Luiz F. Ferreira† Instituto de F́ısica, Universidade Federal do Rio de Janeiro, Caixa Postal 68528, RJ 21941-972 – Brazil Abstract We present a holographic description of the thermal behavior of bb̄ heavy vector mesons inside a plasma at finite temperature and density. The meson dissociation in the medium is represented by the decrease in the height of the spectral functio...

Strongly Coupled QCD at Finite Baryon Density

Finite Density QCD is affected by the well known sign problem that has prevented, in most cases, any success in simulate this theory and, until now, no solution is at sight. The only exceptions in this scenario are strong coupling simulations performed with the Monomer Dimer Polymer (MDP) algorithm [1]. This algorithm is able to provide results not affected by early onset and in partial agreeme...

Medium Modification of the Pion-pion Interaction at Finite Density

We discuss medium modifications of the unitarized pion-pion interaction in the nuclear medium. We incorporate both the effects of chiral symmetry restoration and the influence of collective nuclear pionic modes originating from the p-wave coupling of the pion to delta-hole configurations. We show in particular that the dropping of the sigma meson mass significantly enhances the low energy struc...
