Constraining Right-Handed Scale Through Kaon Mixing in SUSY Left-Right Model

arXiv:0710.1454 · doi:10.1103/PhysRevD.78.035006

Abstract

We study flavor-changing neutral current and CP violations in the minimal supersymmetric left-right model. We calculate the beyond-standard-model contributions to the neutral kaon mixing $ΔM_K$ and $ε$, and find possible to have a numerical cancelation between the contributions from the right-handed gauge boson and supersymmetric box diagram. With the cancelation, the right-handed $W$-boson mass scale can be lowered to about 2 TeV, well within the search limit of LHC.
