Recent Lattice QCD Results from the UKQCD Collaboration
C. R. Allton
The lattice technique of studying the strong interaction of matter is used to obtain predictions of the hadronic spectrum. These simulations were performed by the UKQCD collaborati…
The residual mass in Lattice Heavy Quark Effective Theory to alpha^3 order
F. Di Renzo, L. Scorzato
We determine to order alpha^3 in the quenched approximation the so-called residual mass in the lattice regularisation of the Heavy Quark Effective Theory. We follow a gauge-invaria…
A consistency check for Renormalons in Lattice Gauge Theory: beta^(-10) contributions to the SU(3) plaquette
F. Di Renzo, L. Scorzato
We compute the perturbative expansion of the Lattice SU(3) plaquette to beta^(-10) order. The result is found to be consistent both with the expected renormalon behaviour and with…
Numerical Study of dense adjoint 2-color matter
Simon Hands, Istvan Montvay, Manfred Oevers +2
We study the global symmetries of SU(2) gauge theory with N flavors of staggered fermions in the presence of a chemical potential. We motivate the special interest of the case N=1…
Fermionic Loops in Numerical Stochastic Perturbation Theory
F. Di Renzo, L. Scorzato
We discuss the inclusion of fermionic loops contributions in Numerical Stochastic Perturbation Theory for Lattice Gauge Theories. We show how the algorithm implementation is in pri…
Two-colour QCD at finite fundamental quark-number density and related theories
S. J. Hands, J. B. Kogut, S. E. Morrison +1
We are simulating SU(2) Yang-Mills theory with four flavours of dynamical quarks in the fundamental representation of SU(2) `colour' at finite chemical potential, mu for quark numb…
