Maximal twist and the spectrum of quenched twisted mass lattice QCD
Abdou M. Abdel-Rehim, Randy Lewis, R. M. Woloshyn
Results on the hadron masses for a degenerate doublet of up and down quarks from quenched twisted mass lattice QCD at maximal twist are presented. Two definitions of maximal twist…
The hadron spectrum from twisted mass QCD with a strange quark
Abdou M. Abdel-Rehim, Randy Lewis, R. M. Woloshyn
Various suggestions exist for incorporating the strange quark into twisted mass QCD. One option for quenched simulations is to employ two twisted doublets, (u,d) and (c,s), with se…
Spin splittings among charmed hadrons
Randy Lewis, Nilmani Mathur, R. M. Woloshyn
The mass differences between spin-1/2 and spin-3/2 baryons are compared to the mass differences between spin-0 and spin-1 mesons. Results of simulations for charmed hadrons in the…
