Abstract
The strong constraints on the R-parity conserving supersymmetry (SUSY) from the LHC searches motivate us to consider the new models in which the low-scale SUSY is still allowed. We propose a kind of R-parity violating SUSY scenario with a nonzero ${U}_{2}^{c}{D}_{2}^{c}{D}_{3}^{c}$ operator. Three relevant LHC searches are recast to test the status of this scenario in terms of four simplified models, with either light stop-Bino, stop-Higgsino, sbottom-Bino, or sbottom-Higgsino. Some difficult scenarios for the LHC SUSY searches in these simplified models are identified. By extrapolating the current LHC searches to the future 14 TeV LHC with integrated luminosity of $3000\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$, the stop/sbottom masses in all scenarios can be probed up to $\ensuremath{\sim}800--1100\text{ }\text{ }\mathrm{GeV}$.
Highlights
As one of the most promising candidates for new physics beyond the Standard Model (SM), supersymmetry (SUSY) [1,2] provides an elegant solution to the gauge hierarchy problem
We have shown that the current searches are not yet able to exclude most of the parameter space, especially in thet − Hsimplified model, the b − Bsimplified model, and the Brðb → csÞ 1⁄4 50% scenario in the b − Hsimplified model
We proposed a R-parity violation (RPV) SUSY scenario that is the least constrained by current LHC searches and low energy experiments, in which only the Uc2Dc2Dc3 operator is nonzero
Summary
As one of the most promising candidates for new physics beyond the Standard Model (SM), supersymmetry (SUSY) [1,2] provides an elegant solution to the gauge hierarchy problem. If the RPV couplings are small, such that the R hadrons are stable at the scale of the detector size, there are searches for long-lived R hadrons [21] From those searches, we can observe that the bounds obtained for those operators giving leptons in the final state are quite stringent; e.g., a gluino being excluded up to ∼2 TeV stops being excluded up to ∼1 TeV. We can observe that the bounds obtained for those operators giving leptons in the final state are quite stringent; e.g., a gluino being excluded up to ∼2 TeV stops being excluded up to ∼1 TeV We note that such bounds may be relaxed to some extent by extending the decay chain with extra particles [22,23], due to the soft final states. We show the validation of our recasting of experimental searches in Appendixes A–C
