Instabilities in Molecular Dynamics Integrators used in Hybrid Monte Carlo Simulations
B. Joo, UKQCD Collaboration
We discuss an instability in the leapfrog integration algorithm, widely used in current Hybrid Monte Carlo (HMC) simulations of lattice QCD. We demonstrate the instability in the s…

Semileptonic decay of a heavy-light pseudoscalar to a light vector meson
UKQCD Collaboration, J. Gill
We present the results of a calculation of semileptonic form factors of D and B mesons. The calculation uses nonperturbatively order a improved quenched lattice QCD and two values…
