Abstract
The future electron-proton collider proposals, LHeC and FCC-he, can deliver $\mathcal{O}$(TeV) center-of-mass energy collisions, higher than most of the proposed lepton accelerators, with $\mathcal{O}$(ab$^{-1}$) luminosity, while maintaining a much cleaner experimental environment as compared to the hadron machines. This unique capability of $e^- p$ colliders can be harnessed in probing BSM scenarios giving final states that look like hadronic noise at $pp$ machines. In the present study, we explore the prospects of detecting such a prompt signal having multiple soft jets at the LHeC. Such a signal can come from the decay of gluino in RPV or Stealth SUSY, where there exists a gap in the current experimental search with $m_{\tilde{g}} \approx 50 - 70$ GeV. We perform a simple analysis to demonstrate that, with simple signal selection cuts, we can close this gap at the LHeC at 95 % confidence level, even in the presence of a reasonable systematic error. More sophisticated signal selection strategies and detailed knowledge of the detector can be used to improve the prospects of signal detection.
Highlights
The search for new physics that can address fundamental problems in the Standard Model (SM) like the hierarchy problem, dark matter, baryon asymmetry etc., depends crucially on the development of experiments capable of probing new regimes
The unique feature of these future e−p colliders is that their proposed center-of-mass energies (1.3 and 3.5 TeV at the Large Hadron electron Collider (LHeC) and Future Circular hadron-electron Collider (FCC-he), respectively) are much higher than that of most of the proposed lepton colliders, along with ∼1 ab−1 total luminosity, while maintaining a clean experimental environment with much less QCD background and pileup as compared to the hadron colliders
Apart from doing more precise measurements of parton distribution functions (PDFs), this capability of e−p colliders can be harnessed in searches for new physics. This can be useful in probing beyond the Standard Model (BSM) scenarios which provide signal final states that look like hadronic noise at the pp colliders, making them very hard to probe
