摘要:Using the O(a) Symanzik improved action an estimate is given for the strange quark mass for
unquenched (nf =2) QCD. The determination is via the axialWard identity (AWI) and includes a
non-perturbative evaluation of the renormalisation constant. Numerical results have been obtained
at several lattice spacings, enabling the continuum limit to be taken. Results indicate a value for
the strange quark mass (in the MS-scheme at a scale of 2MeV) in the range 100 – 130MeV.
