Classical Simulation of Quantum Fields II
T. Hirayama, B. Holdom, R. Koniuk +1
We consider the classical time evolution of a real scalar field in 2 dimensional Minkowski space with a interaction. We compute the spatial and temporal two-point correlatio…
Less naive about supersymmetric lattice quantum mechanics
Joel Giedt, Roman Koniuk, Erich Poppitz +1
We explain why naive discretization results that have appeared in [hep-lat/0006013] do not appear to yield the desired continuum limit. The fermion propagator on the lattice inevit…
Unquenched Charmonium with NRQCD - Lattice 2000
Chris Stewart, Roman Koniuk
We present results from a series of NRQCD simulations of the charmonium system, both in the quenched approximation and with n_f = 2 dynamical quarks. The spectra show evidence for…
Unquenched Charmonium with NRQCD
Chris Stewart, Roman Koniuk
We present the results from a series of lattice simulations of the charmonium system using a highly-improved NRQCD action, both in the quenched approximation, and with n_f = 2 ligh…
Pushing NRQCD to the limit
Chris Stewart, Roman Koniuk
Lattice NRQCD has proven successful in describing the physics of the upsilon system and B-mesons, though some concerns arise when it is used in simulations of charm quarks. It is c…
String-breaking in quenched QCD
Chris Stewart, Roman Koniuk
We present results on a new operator for the investigation of string-breaking effects in quenched SU(2)-colour QCD. The ground state of a spatially-separated static-light meson-ant…
