Perturbative Renormalization of Neutron-Antineutron Operators

  title={Perturbative Renormalization of Neutron-Antineutron Operators},
  author={Michael I. Buchoff and Michael Wagman},
  journal={Physical Review D},
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…

Lattice QCD determination of neutron-antineutron matrix elements with physical quark masses
Matrix elements of six-quark operators are needed to extract new physics constraints from experimental searches for neutron-antineutron oscillations. This work presents in detail the first lattice
Neutron-Antineutron Oscillations from Lattice QCD.
First-principles calculations of neutron-antineutron matrix elements needed to accurately connect measurements of the neutron-anticutron oscillation rate to constraints on |ΔB|=2 baryon number violation in BSM theories are presented.
Baryon number violation in supersymmetry: Neutron-antineutron oscillations as a probe beyond the LHC
We summarize the current status of baryon number violation in supersymmetry and provide prospects for going beyond the present reach by means of a new search for neutron-antineutron oscillations. The

Baryon-Number Violation by Two Units and the Deuteron Lifetime.
An effective field theory for |ΔB|=2 interactions that give rise to neutron-antineutron (n-n[over ¯]) oscillations and dinucleon decay within a consistent power counting is constructed.
Super-light baryphotons, Weak Gravity Conjecture and Exotic instantons in Neutron-Antineutron transitions
In companion papers \cite{Addazi:2015pia,Addazi:2016rgo}, we have discussed current bounds of a new super-light baryo-photon, associated to a $U(1)_{B-L}$ gauged, from neutron-antineutron current
Implications of an Improved Neutron-Antineutron Oscillation Search for Baryogenesis: A Minimal Effective Theory Analysis.
It is found that even in a minimal EFT setup there is overlap between the parameter space probed by n-n[over ¯] oscillation and the region that can realize the observed baryon asymmetry of the Universe.
