Non-perturbative determination of improvement coefficients b_m and b_A-b_P and normalisation factor Z_m*Z_P/Z_A with N_f=3 Wilson fermions
We determine non-perturbatively the normalisation parameter $Z_\mathrm{m}Z_\mathrm{P}/Z_\mathrm{A}$ as well as the Symanzik coefficients $b_\mathrm{m}$ and $b_\mathrm{A}-b_\mathrm{P}$ , required in $\mathrm{O}(a)$ improved quark mass renormalisation with Wilson fermions. The strategy underlying thei...
