Elastic scattering in the channel
Constantia Alexandrou, Kyriakos Hadjiannakou, Giannis Koutsou +4
We present our study of scattering in the iso-spin channel for the first time at the physical point. The calculation is performed using flavors of twisted…
Pion-pole contribution to HLbL from twisted mass lattice QCD at the physical point
Sebastian Burri, Constantia Alexandrou, Simone Bacchio +13
We report on our computation of the pion transition form factor from twisted mass lattice QCD in order to determine the numerically dominant light…
Hadronic Parity Violation from 4-quark Interactions
Aniket Sen, Marcus Petschlies, Nikolas Schlage +1
We present an exploratory investigation of the parity odd pion-nucleon coupling from lattice QCD. Based on the PCAC relation, we study the parity-conserving effect…
Quark and gluon momentum fractions in the pion from lattice QCD
Constantia Alexandrou, Simone Bacchio, Georg Bergner +11
We perform the first full decomposition of the pion momentum into its gluon and quark contributions. We employ an ensemble generated by the Extended Twisted Mass Collaboration with…
P-wave nucleon-pion scattering amplitude in the channel from lattice QCD
Giorgio Silvi, Srijit Paul, Constantia Alexandrou +9
We determine the resonance parameters using lattice QCD and the Lüscher method. The resonance occurs in elastic pion-nucleon scattering with in the isospin $I…
