Strangeness in the nucleon from a mixed action calculation
Michael Engelhardt
TL;DR
This paper investigates the contributions of strange quarks to the nucleon mass and spin using a mixed action lattice QCD approach with domain wall valence quarks on MILC asqtad ensembles, at pion masses of 495 and 356 MeV.
Contribution
It introduces a mixed action calculation method to study strange quark contributions to nucleon properties, providing new lattice QCD results.
Findings
Strange quark contributions to nucleon mass quantified.
Strange quark contributions to nucleon spin estimated.
Results at two different pion masses presented.
Abstract
The contributions of strange quarks to the nucleon mass and the nucleon spin are investigated in a mixed action scheme employing domain wall valence quarks and quark loops on MILC asqtad dynamical fermion ensembles. Results are presented for pion masses 495 MeV and 356 MeV.
