Description
Defining a renormalisation process that incorporates mixing between connected and disconnected operators, both in the quark and gluon sectors, relies on measuring disconnected operators inserted on bare lattice quark and gluon propagators. In this talk, I will discuss calculations of these operators through Feynman-Hellmann techniques, and the results of renormalised hadronic operators when considering the full mixing matrix, in both quenched and dynamical lattice QCD simulations.
