Lattice determination of the Batalin-Vilkovisky function and the strong running interaction
A. C. Aguilar, N. Brito, M. N. Ferreira +3
The Batalin-Vilkovisky function is a central component in the modern formulation of the background field method and the physical applications derived from it. In the present work w…
Gluon and Ghost Dynamics from Lattice QCD
O. Oliveira, A. G. Duarte, D. Dudal +1
The two point gluon and ghost correlation functions and the three gluon vertex are investigated, in the Landau gauge, using lattice simulations. For the two point functions, we dis…
The Landau gauge gluon propagator at zero and finite temperature: accounting for the combined finite lattice spacing and finite volume effects
O. Oliveira, P. J. Silva
In the past years a good comprehension of the infrared gluon propagator has been achieved, with a good qualitative agreement between lattice results and Dyson-Schwinger equations.…
Glueball spectral densities from the lattice
O. Oliveira, D. Dudal, P. J. Silva
The propagator of a physical degree of freedom ought to obey a Källén-Lehmann spectral representation, with positive spectral density. The latter quantity is directly related to a…
Unquenching the Landau Gauge Lattice Propagators and the Gribov Problem
P. J. Silva, O. Oliveira
The gluon and ghost propagators are computed using both quenched and dynamical configurations for the same lattice spacings. The Wilson fermions are simulated at several quark mass…
Better HMC integrators for dynamical simulations
M. A. Clark, Balint Joo, A. D. Kennedy +1
We show how to improve the molecular dynamics step of Hybrid Monte Carlo, both by tuning the integrator using Poisson brackets measurements and by the use of force gradient integra…
