Abstract

We describe an ongoing project by the QCDSF collaboration to calculate baryon wave functions at small inter-quark separation using lattice QCD. Preliminary results are presented for the wave functions at the origin and momentum fractions carried by the valence quarks in the nucleon and its negative parity partner, N* (1535). The calculations are done using two flavors of dynamical (clover) fermions on lattices of different volume and pion masses down to mπ ≃ 180 MeV. [ABSTRACT FROM AUTHOR]

Abstract

We present results obtained in QCD with two flavors of non-perturbatively improved Wilson fermions at finite temperature on 163 × 8 and 243 × 10 lattices. We determine the transition temperature in the range of quark masses 0.6 < mπ/mρ < 0.8 at lattice spacing a≈0.1 fm and extrapolate the transition temperature to the continuum and to the chiral limits. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR]
