Description
Nucleon matrix elements are a major lattice QCD input to the search of new physics. Their determination can be challenging, in particular at near physical quark masses. On the one hand large Euclidean time separations are necessary to determine ground state matrix elements. On the other hand the signal over noise ratio deteriorates exponentially with the time. I will detail some of the techniques our group use for the efficient calculation of quark line disconnected as well as of connected contributions to various matrix elements.
