Pseudoscalar-pole contributions to the muon at the physical point

Sebastian Burri, Gurtej Kanwar, Constantia Alexandrou +14

Pseudoscalar-pole diagrams are an important component of estimates of the hadronic light-by-light (HLbL) contribution to the muon . We report on our computation of the transit…

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…

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…

Excited states in nucleon structure calculations

Konstantin Ottnad

Excited state contributions represent a formidable challenge for hadron structure calculations in lattice QCD. For physical systems that exhibit an exponential signal-to-noise prob…

On the generalised eigenvalue method and its relation to Prony and generalised pencil of function methods

Matthias Fischer, Bartosz Kostrzewa, Johann Ostmeyer +3

We discuss the relation of three methods to determine energy levels in lattice QCD simulations: the generalised eigenvalue, the Prony and the generalised pencil of function methods…

Pseudoscalar flavor-singlet mesons from lattice QCD

Konstantin Ottnad

We investigate the masses and mixing of , mesons in the framework of twisted mass lattice QCD with dynamical quark flavors. For the first time we perform a cont…
