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…
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…
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…
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 t…
The strong coupling constant: State of the art and the decade ahead
D. d'Enterria, S. Kluth, G. Zanderighi +55
Theoretical predictions for particle production cross sections and decays at colliders rely heavily on perturbative Quantum Chromodynamics (QCD) calculations, expressed as an expan…
