EJElizabeth JenkinsAMAneesh V. ManoharMTMichael Trott

Key Points

  • This research aims to analyze the effects of dimension-six operators in the Standard Model through the calculation of their anomalous dimensions.
  • Calculated the one-loop anomalous dimension matrix for 59 dimension-six operators at order λ, λ², and λy².
  • Investigated operator mixing due to equations of motion and how it affects running parameters.
  • Computed the complete one-loop anomalous dimension matrix, revealing novel mixing between certain operators.
  • Demonstrated that dimension-six operators significantly influence the running of Standard Model parameters.

Abstract

A bstract We calculate the order λ, λ 2 and λ y 2 terms of the 59 × 59 one-loop anomalous dimension matrix of dimension-six operators, where λ and y are the Standard Model Higgs self-coupling and a generic Yukawa coupling, respectively. The dimension-six operators modify the running of the Standard Model parameters themselves, and we compute the complete one-loop result for this. We discuss how there is mixing between operators for which no direct one-particle-irreducible diagram exists, due to operator replacements by the equations of motion.
