Inclusive P-wave Quarkonium Decay Widths from Lattice QCD and pNRQCD

Nora Brambilla, Viljami Leino, Julian Mayer-Steudte +4

Inclusive hadronic decay widths remain a long-standing challenge for first-principles QCD. We present a framework combining lattice QCD with strongly-coupled potential nonrelativis…

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…

Wilson loops with neural networks

Verena Bellscheidt, Nora Brambilla, Andreas S. Kronfeld +1

Wilson loops are essential objects in QCD and have been pivotal in scale setting and demonstrating confinement. Various generalizations are crucial for computations needed in effec…

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…

Quenched Static force from generalized Wilson loops with gradient flow

Julian Mayer-Steudte

We compute the static force on the lattice in the quenched case directly through generalized Wilson loops. We modify the Wilson loop by inserting an -field component on one of t…

Static force from generalized Wilson loops on the lattice using the gradient flow

Nora Brambilla, Viljami Leino, Julian Mayer-Steudte +1

The static QCD force from the lattice can be used to extract , which determines the running of the strong coupling. Usually, this is done with a numeric…

Implications of gradient flow on the static force

Nora Brambilla, Viljami Leino, Julian Mayer-Steudte +1

We use gradient flow to compute the static force based on a Wilson loop with a chromoelectric field insertion. The result can be compared on one hand to the static force from the n…

Heavy quark diffusion coefficient with gradient flow

Viljami Leino, Nora Brambilla, Julian Mayer-Steudte +1

The heavy quark diffusion coefficient is encoded in the spectral functions of the chromo-electric and the chromo-magnetic correlators, of which the latter describes the T/M contrib…

Chromoelectric and chromomagnetic correlators at high temperature from gradient flow

Julian Mayer-Steudte, Nora Brambilla, Viljami Leino +1

The heavy quark diffusion coefficient is encoded in the spectral functions of the chromoelectric and the chromomagnetic correlators that are calculable on the lattice. We study the…

The static force from generalized Wilson loops using gradient flow

Viljami Leino, Nora Brambilla, Julian Mayer-Steudte +1

We explore a novel approach to compute the force between a static quark-antiquark pair with the gradient flow algorithm on the lattice. The approach is based on inserting a chromoe…
