摘要: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 separate twist
angles. Working in the isospin limit, preliminary results for the quenched spectrum of strange
hadrons are presented, with both twist angles tuned to p=2. Splittings within the mass multiplets
provide some insight into the symmetry breaking effects of twisted mass lattice QCD.
