Renormalization of composite operators (A04)

• Subject Area: Nuclear and Elementary Particle Physics, Quantum Mechanics, Relativity, Fields

Many important hadronic observables are derived from matrix elements of local operators composed of quark and gluon fields. In the present project we compute the renormalization coefficients for such operators. These coefficients are required to convert the bare lattice results to physical quantities, which can be compared with experiment. The computations are performed with nonperturbative methods, i.e., variants of the Rome-Southampton approach.
