Finite Temperature Sum Rules in Lattice Gauge Theory
Harvey B. Meyer
We derive non-perturbative sum rules in SU() lattice gauge theory at finite temperature. They relate the susceptibilities of the trace anomaly and energy-momentum tensor to temp…
A calculation of the bulk viscosity in SU(3) gluodynamics
Harvey B. Meyer
We perform a lattice Monte-Carlo calculation of the trace-anomaly two-point function at finite temperature in the SU(3) gauge theory. We obtain the long-distance properties of the…
The Glue Content of the Pion
Harvey B. Meyer, John W. Negele
We perform a quenched computation of the glue momentum fraction in the pion. Different discretizations of the gluonic energy-momentum tensor are studied on the lattice for that pur…
Gluon contributions to the pion mass and light cone momentum fraction
Harvey B. Meyer, John W. Negele
We calculate the matrix elements of the gluonic contributions to the energy-momentum tensor for a pion of mass 600 < Mpi < 1100 MeV in quenched lattice QCD. We find that gluons con…
Non-perturbative renormalization of the chromo-magnetic operator in Heavy Quark Effective Theory and the B* - B mass splitting
Damiano Guazzini, Harvey B. Meyer, Rainer Sommer
We carry out the non-perturbative renormalization of the chromo-magnetic operator in Heavy Quark Effective Theory. At order 1/m of the expansion, the operator is responsible for th…
