The heavy quarks self energy from moving NRQCD on the lattice


Abstract in English

We present a calculation of the heavy quarks self energy in moving NRQCD to one-loop in perturbation theory. Results for the energy shift and external momentum renormalisation are discussed and compared with non-perturbative results. We show that the momentum renormalisation is small, which is the result of a remnant of re-parameterisation invariance on the lattice.
