Strong coupling constant from the 1-loop improved static energy
Viljami Leino, Alexei Bazavov, Nora Brambilla +8
The static energy is an excellent observable for extracting the strong coupling on the lattice. For short distances, the static energy can be calculated both on the lattice u…
Neural network interpolators for Wilson loops
Julian Mayer-Steudte
The extraction of the static quark-antiquark potential from lattice QCD suffers from the poor signal-to-noise ratio of Wilson loops at large Euclidean times. To overcome this, smea…
Lattice study of correlators for quarkonium decay
Saumen Datta, Debasish Banerjee, Nora Brambilla +6
While there has been a lot of progress in developing a formalism for the study of quarkonia in QGP, a nonperturbative study is still difficult. For bottomonia, where the system siz…
Adjoint chromoelectric correlators for heavy quarkonium diffusion
Julian Mayer-Steudte
We here measure, for the first time, adjoint chromoelectric correlators at finite temperatures that encode the diffusion of quarkonium in the medium. Understanding the dynamics of…
Lattice study of correlators of chromoelectric fields for heavy quarkonium dynamics in the quark-gluon plasma
Nora Brambilla, Saumen Datta, Marc Janer +4
We perform a lattice calculation of the correlators of two chromoelectric fields in the adjoint representation connected by adjoint Wilson lines at non-zero temperature. These corr…
Strong coupling in (2+1+1)-flavor QCD
Viljami Leino, Alexei Bazavov, Nora Brambilla +6
The strong coupling can be obtained from the static energy as shown in previous lattices studies. For short distances, the static energy can be calculated both on th…
