Collider Phenomenology of Light Strange-beauty Squarks

Abstract

Strong mixing between right-handed strange and beauty squarks is a possible solution to the CP violation discrepancy in $B\to \varphi K_S$ decay as recently suggested by the Belle data. In this scenario, thanks to the strong mixing one of the strange-beauty squarks can be as light as 200 GeV, even though the generic supersymmetry scale is at TeV. In this work, we study the production of this light right-handed strange-beauty squark at hadronic colliders and discuss the detection in various decay scenarios. Detection prospect at the Tevatron Run II is good for the strange-beauty squark mass up to about 300 GeV.
