Heavy Quark Diffusion and Lattice Correlators

P. Petreczky, K. Petrov, D. Teaney +1

We study charmonia correlators at finite temperature. We analyze to what extent heavy quarkonia correlators are sensitive to the effect of heavy quark transport and whether it is p…

Quarkonium correlators and spectral functions at zero and finite temperature

A. Jakovac, P. Petreczky, K. Petrov +1

We study quarkonium correlators and spectral functions at zero and finite temperature using the anisotropic Fermilab lattice formulation with anisotropy xi=2 and 4. To control cuto…

Low-temperature expansion and perturbation theory in 2D models with unbroken symmetry: a new approach

O. Borisenko, V. Kushnir, A. Velytsky

A new method of constructing a weak coupling expansion of two dimensional (2D) models with an unbroken continuous symmetry is developed. The method is based on an analogy with the…

Bottomonia correlators and spectral functions at zero and finite temperature

K. Petrov, A. Jakovac, P. Petreczky +1

We present preliminary studies of bottomonia spectral functions at zero and finite temperature using quenched anisotropic lattices. The heavy quark is treated within Fermilab appro…

Fisher's zeros of quasi-Gaussian densities of states

A. Denbleyker, D. Du, Y. Meurice +1

We discuss apparent paradoxes regarding the location of the zeros of the partition function in the complex plane (Fisher's zeros) of a pure SU(2) lattice gauge theory in 4 dim…

Static quark anti-quark pair in SU(2) gauge theory

A. Bazavov, P. Petreczky, A. Velytsky

We study singlet and triplet correlation functions of static quark anti-quark pair defined through gauge invariant time-like Wilson loops and Polyakov loop correlators in finite te…
