Zusammenfassung
Hadrons in lattice QCD are usually created employing smeared interpolators. We introduce a new quark smearing that allows us to maintain small statistical errors and good overlaps of hadronic wave functions with the respective ground states, also at high spatial momenta. The method is successfully tested for the pion and the nucleon at a pion mass m(pi) approximate to 295 MeV and momenta as high ...
Zusammenfassung
Hadrons in lattice QCD are usually created employing smeared interpolators. We introduce a new quark smearing that allows us to maintain small statistical errors and good overlaps of hadronic wave functions with the respective ground states, also at high spatial momenta. The method is successfully tested for the pion and the nucleon at a pion mass m(pi) approximate to 295 MeV and momenta as high as 2.8 GeV. We compare the results obtained to dispersion relations and suggest further optimizations.
