Parton physics from a heavy-quark operator product expansion: Lattice QCD calculation of the second moment of the pion distribution amplitude [PDF]

open access: yesPhysical Review D, 2021
The pion light-cone distribution amplitude (LCDA) is a central non-perturbative object of interest for high-energy exclusive processes in quantum chromodynamics.

Soft-parton contributions to heavy-quark production at low transverse momentum [PDF]

open access: yesJournal of High Energy Physics, 2023
We consider QCD radiative corrections to the production of a heavy-quark pair in hadronic collisions. We present the computation of the soft-parton contributions at low transverse momentum of the heavy-quark pair up to second order in the QCD coupling α ...

Heavy-quark diffusion in the quark–gluon plasma [PDF]

open access: yesProgress in Particle and Nuclear Physics, 2022
The diffusion of heavy quarks through the quark-gluon plasma (QGP) as produced in high-energy heavy-ion collisions has long been recognized as an excellent probe of its transport properties.

Heavy quark fragmentation in e+e− collisions to NNLO+NNLL accuracy in perturbative QCD [PDF]

open access: yesJournal of High Energy Physics, 2023
Fragmentation of heavy quarks into heavy-flavoured hadrons receives both perturbative and non-perturbative contributions. We consider perturbative QCD corrections to heavy quark production in e+e− collisions to next-to-next-to-leading order accuracy in ...

Theory of the (Heavy-Quark) Exotic Hadrons: A Primer for the Flavor Community [PDF]

open access: yesProceedings of 21st Conference on Flavor Physics and CP Violation — PoS(FPCP2023), 2023
Scores of exotic hadrons, particularly tetraquarks and pentaquarks in the heavy-quark sector, have been observed in the past 20 years, and more continue to be discovered to this day. Unlike mesons and baryons, such exotics are not mandated to exist under

Flavor Anomalies in Heavy Quark Decays [PDF]

open access: yes, 2021
Recent measurements of b-hadron decays show a pattern of consistent tensions with the respective Standard Model (SM) predictions. These tensions appear both in the sector of rare flavourchanging neutral currents and in tree-level semileptonic b-hadron ...
