Bilinear quark operators in the RI/SMOM scheme at three loops

Physics Letters B, 2020
We consider the renormalization of the matrix elements of the bilinear quark operators ψ¯ψ, ψ¯γμψ, and ψ¯σμνψ at next-to-next-to-next-to-leading order in QCD perturbation theory at the symmetric subtraction point.

Heavy-Meson Decay Constants: QCD Sum-Rule Glance at Isospin Breaking

EPJ Web of Conferences, 2016
QCD sum rules for decay constants of heavy mesons with u or d quark yield for B mesons much less isospin breaking than lattice QCD but good agreement for D mesons.

Recent developments in lattice QCD [PDF]

Pramana, 1993
I review the current status of lattice QCD results. I concentrate on new analytical developments and on numerical results relevant to phenomenology.

Resonances from lattice QCD

EPJ Web of Conferences, 2018
The spectrum of hadron is mainly composed as shortly-lived states (resonance) that decay onto two or more hadrons. These resonances play an important role in a variety of phenomenologically significant processes.

Machine learning insights into quark–antiquark interactions: probing field distributions and string tension in QCD

European Physical Journal C: Particles and Fields
Understanding the interactions between quark–antiquark pairs is essential for elucidating quark confinement within the framework of quantum chromodynamics (QCD).

Neutron Electric Dipole Moment on the Lattice

EPJ Web of Conferences, 2018
For the neutron to have an electric dipole moment (EDM), the theory of nature must have T, or equivalently CP, violation. Neutron EDM is a very good probe of novel CP violation in beyond the standard model physics.
