Higgs boson enhancement effects on squark-pair production at the LHC

Arhrib, Abdesslam, Benbrik, Rachid, Cheung, Kingman et al.

Understand

We study the Higgs boson effects on third-generation squark-pair production in proton-proton collision at the CERN Large Hadron Collider (LHC), including $\Stop \Stop^*$, $\Stop\Sbot^*$, and $\Sbot \Sbot^*$.

We found that substantial enhancement can be obtained through s-channel exchanges of Higgs bosons at large $\tan\beta$, at which the enhancement mainly comes from $b\bar b$, $b\bar c$, and $c\bar b$ initial states.
We compute the complete set of electroweak (EW) contributions to all production channels.
This completes previous computations in the literature.
