# Perturbative Renormalization of Neutron-Antineutron Operators

@article{Buchoff2016PerturbativeRO, title={Perturbative Renormalization of Neutron-Antineutron Operators}, author={Michael I. Buchoff and Michael Wagman}, journal={Physical Review D}, year={2016}, volume={93}, pages={016005} }

Two-loop anomalous dimensions and one-loop renormalization scheme matching factors are calculated for six-quark operators responsible for neutron-antineutron transitions. When combined with lattice QCD determinations of the matrix elements of these operators, our results can be used to reliably predict the neutron-antineutron vacuum transition time, $\tau_{n\bar{n}}$, in terms of basic parameters of baryon-number violating beyond-the-Standard-Model theories. The operators are classified by…
