Pion photoproduction of nucleon excited states with Hamiltonian effective field theory [PDF]

EPJ Web of Conferences
Over the past few years, Hamiltonian effective field theory has been successfully applied to studies of nucleon and hyperon excited states. By discretizing the Hamiltonian in a finite volume, one can obtain the energy spectrum and compare it with the ...

Heavy quark physics on the lattice with improved nonrelativistic actions [PDF]

, 2010
Hadrons containing heavy quarks, in particular b quarks, play an important role in high energy physics. Measurements of their electroweak interactions are used to test the Standard Model and search for new physics.

Update on ɛK with lattice QCD inputs

EPJ Web of Conferences, 2018
We report updated results for ɛK, the indirect CP violation parameter in neutral kaons, which is evaluated directly from the standard model with lattice QCD inputs. We use lattice QCD inputs to fix B⌢K,Vcb,ξ0,ξ2,Vus, and mc(mc).

Odd-spin glueballs, AdS/QCD and information entropy

Physics Letters B, 2020
Odd-spin glueballs in the dynamical AdS/QCD model are scrutinized, in the paradigm of the configurational entropy (CE). Configurational-entropic Regge trajectories, that relate the CE underlying odd-spin glueballs to their mass spectra and spin, are then

Lattice QCD Overview [PDF]

EPJ Web of Conferences
I review recent progress in lattice QCD calculations of the QCD phase diagram and equation of state at non-zero temperature and baryochemical potential. I also discuss some connections with heavy ion collisions.

Vacuum correlators at short distances from lattice QCD

Journal of High Energy Physics, 2021
Non-perturbatively computing the hadronic vacuum polarization at large photon virtualities and making contact with perturbation theory enables a precision determination of the electromagnetic coupling at the Z pole, which enters global electroweak fits ...

Heavy-hadron interactions from Lattice QCD

EPJ Web of Conferences, 2018
I review recent progress in heavy hadron spectroscopy and from ab-initio Lattice QCD calculations.After motivating lattice calculations for heavy-hadrons by contrasting recent LHCb results charmed and doubly-charmed baryons with lattice predictions ...
