摘要：We present results on the mass of the baryon octet and decuplet using two flavors of light dynamical
twisted mass fermions. The strange quark mass is fixed to its physical value from the kaon
sector in a partially quenched set up. Calculations are performed for light quark masses corresponding
to a pion mass in the range 270-500 MeV and lattice sizes of 2.1 fm and 2.7 fm. We
check for cut-off effects and isospin breaking by evaluating the baryon masses at two different
lattice spacings. We carry out a chiral extrapolation for the octet baryons and discuss results for
the W.
