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…
Extraction of charmonium branching fractions from radiative decays
Magnus C. Schaaf, Antonio Vairo
We assess the tension between theoretical predictions and the values quoted by the Particle Data Group (PDG) for the partial decay width and branching fraction associated with the…
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…
Open-flavor threshold effects on quarkonium spectrum in the BOEFT
Nora Brambilla, Abhishek Mohapatra, Tommaso Scirpa +1
The impact of open-flavor thresholds on the quarkonium spectrum has been a subject of study since the introduction of the Cornell potential and has been quantified through various…
Inclusive hadroproduction of , and pentaquarks
Nora Brambilla, Mathias Butenschoen, Simon Hibler +3
We use the Born--Oppenheimer effective field theory factorization to compute the inclusive production cross sections of the and its partner in the bottomonium secto…
Born-Oppenheimer EFT: a unified description of ordinary and exotic quarkonia
Antonio Vairo
We show how the Born-Oppenheimer effective field theory (BOEFT) provides a unified description of ordinary and exotic quarkonia grounded on the non-relativistic expansions of QCD a…
