We present an exploratory numerical study on the lattice of the color structure of the wave functionals of the SU(3) Yang-Mills theory in the presence of a static pair. I…
QED Corrections to Hadronic Processes in Lattice QCD
N. Carrasco, V. Lubicz, G. Martinelli +4
In this paper, for the first time a method is proposed to compute electromagnetic effects in hadronic processes using lattice simulations. The method can be applied, for example, t…

Giancarlo Rossi, Massimo Testa
We prove that the stress tensor, tau^{ab}, of a molecular system with arbitrary, short-range interactions can be point-wisely expressed as the functional derivative of the partitio…
