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…
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 sector…
Hidden self-energy contributions of collinear functions in SCET
Geoffrey T. Bodwin, June-Haak Ee, Daekyoung Kang +1
The LSZ reduction formula requires one to identify and amputate complete propagators on external legs of a Green's function and to evaluate complete two-point functions in the mass…
How well does nonrelativistic QCD factorization work at next-to-leading order?
Nora Brambilla, Mathias Butenschoen, Xiang-Peng Wang
We perform a thorough investigation of the universality of the long distance matrix elements (LDMEs) of nonrelativistic QCD factorization based on a next-to-leading order (NLO) fit…

Zexuan Chu, Jinhui Chen, Xiang-Peng Wang +1
Within the framework of non-relativistic QCD (NRQCD) effective field theory, we study the leptoproduction of at next-to-leading order in perturbative QCD for both unpolarized…
Off-lightcone Wilson-line operators in gradient flow
Nora Brambilla, Xiang-Peng Wang
Off-lightcone Wilson-line operators are constructed using local operators connected by time-like or space-like Wilson lines, which ensure gauge invariance. Off-lightcone Wilson-lin…

We outline the physics opportunities provided by the Electron Ion Collider (EIC). These include the study of the parton structure of the nucleon and nuclei, the onset of gluon satu…
Gauge invariance of radiative jet functions in the position-space formulation of SCET
Geoffrey T. Bodwin, June-Haak Ee, Daekyoung Kang +1
In subleading powers of soft-collinear effective theory (SCET), the Lagrangian contains couplings between soft quarks and hard-collinear quarks. Matrix elements of the hard-colline…

We review our recent study on the QCD static force using gradient flow at next-to-leading order in the strong coupling. The QCD static force has the advantage of being free of the…

Under some assumptions on the hierarchy of relevant energy scales, we compute the nonrelativistic QCD (NRQCD) long-distance matrix elements (LDMEs) for inclusive production of $J/ψ…

We compute the QCD static force and potential using gradient flow at next-to-leading order in the strong coupling. The static force is the spatial derivative of the static potentia…
