Mixed Action Effective Field Theory: an Addendum
Jiunn-Wei Chen, Maarten Golterman, Donal O'Connell +1
We correct a mistake in the literature regarding the additive lattice spacing corrections to the mixed valence-sea meson mass and discuss the consequences for mixed action extrapol…
pi-pi Scattering in Twisted Mass Chiral Perturbation Theory
Michael I Buchoff, Jiunn-Wei Chen, Andre Walker-Loud
In this report we describe both I=2 and I=0 pi-pi scattering for twisted mass lattice QCD utilizing twisted mass chiral perturbation theory at next-to-leading order. Focusing on th…
Generalised parton distributions of the pion in partially-quenched chiral perturbation theory
Jiunn-Wei Chen, William Detmold, Brian Smigielski
We consider the pion matrix elements of the isoscalar and isovector combinations of the vector and tensor twist-two operators that determine the moments of the various pion general…
Two Meson Systems with Ginsparg-Wilson Valence Quarks
Jiunn-Wei Chen, Donal O'Connell, Andre Walker-Loud
Unphysical effects associated with finite lattice spacing and partial quenching may lead to the presence of unphysical terms in chiral extrapolation formulae. These unphysical term…
