Inclusive P-wave Quarkonium Decay Widths from Lattice QCD and pNRQCD
Nora Brambilla, Viljami Leino, Julian Mayer-Steudte +4
The paper develops a method that combines lattice QCD with potential nonrelativistic QCD to calculate inclusive decay widths of P‑wave heavy quarkonium states, determining a key no…
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…
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…
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…
