Long-distance hybrid spin-dependent and hybrid-quarkonium mixing potentials from lattice gauge theory
Vilija de Jonge, Paul Pütz, Antonio Vairo +1
We present lattice gauge theory results for the hybrid spin-dependent and hybrid-quarkonium mixing potentials. The only existing lattice computation of…
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…
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 th…
