Wilson flow and scale setting from lattice QCD

V. G. Bornyakov, R. Horsley, R. Hudspith +8

We give a determination of the phenomenological value of the Wilson (or gradient) flow scales t0 and w0 for 2+1 flavours of dynamical quarks. The simulations are performed keeping…

Partially conserved axial vector current and applications

R. Horsley, S. Kazmin, Y. Nakamura +5

We investigate implications of the use of the point-split axial vector current derived from a Wilson like fermionic action. We compute the corresponding renormalization factor nonp…

Hyperon sigma terms for 2+1 quark flavours

R. Horsley, Y. Nakamura, H. Perlt +7

QCD lattice simulations determine hadron masses as functions of the quark masses. From the gradients of these masses and using the Feynman-Hellmann theorem the hadron sigma terms c…

Two-point functions of quenched lattice QCD in Numerical Stochastic Perturbation Theory. (I) The ghost propagator in Landau gauge

F. Di Renzo, E. -M. Ilgenfritz, H. Perlt +2

This is the first of a series of two papers on the perturbative computation of the ghost and gluon propagators in SU(3) Lattice Gauge Theory. Our final aim is to eventually compare…

The Drell-Yan process and Deep Inelastic Scattering from the lattice

M. Goeckeler, R. Horsley, E. -M. Ilgenfritz +6

We report on measurements of the h_1 structure function, relevant to calculating cross-sections for the Drell-Yan process. This is a quantity which can not be measured in Deep Inel…

Detailed Phase Transition Study at M_H <= 70 GeV in a 3-dimensional --Higgs Model

M. Gürtler, E. -M. Ilgenfritz, J. Kripfganz +2

We study the electroweak phase transition in an effective 3-dimensional theory for a Higgs mass of about 70 GeV by Monte Carlo simulations. The transition temperature and jumps of…
