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…
K to pi and K to 0 in 2+1 Flavor Partially Quenched Chiral Perturbation Theory
C. Aubin, J. Laiho, S. Li +1
We calculate results for K to pi and K to 0 matrix elements to next-to-leading order in 2+1 flavor partially quenched chiral perturbation theory. Results are presented for both the…
Kaon Condensation with Lattice QCD
William Detmold, Kostas Orginos, Martin J. Savage +1
Kaon condensation may play an important role in the structure of hadronic matter at densities greater than that of nuclear matter, as exist in the interior of neutron stars. We pre…
Hadronic Interactions from Lattice QCD
Silas R. Beane, Kostas Orginos, Martin J. Savage
We present an overview of recent efforts to calculate the interactions among hadrons using lattice QCD. After outlining the techniques that are used to extract scattering parameter…
Multi-Pion States in Lattice QCD and the Charged-Pion Condensate
William Detmold, Martin J. Savage, Aaron Torok +4
The ground-state energies of systems containing up to twelve 's in a spatial volume V ~ (2.5 fm)^3 are computed in dynamical, mixed-action lattice QCD at a lattice spacing of…
