Searches for Pair-Produced Multijet Resonances Using Data Scouting in Proton-Proton Collisions at sqrt[s]=13  TeV

Area of Science:

• High Energy Physics
• Particle Physics
• Supersymmetry

Background:

• Searches for new physics beyond the Standard Model are crucial.
• Supersymmetry (SUSY) is a leading theoretical extension.
• R-parity violating (RPV) SUSY models offer unique signatures.

Purpose of the Study:

• To search for pair-produced multijet signatures in RPV SUSY models.
• To probe electroweak production of RPV SUSY particles with fully hadronic final states.
• To perform the first search for prompt hadronically decaying mass-degenerate higgsinos.

Main Methods:

• Utilized data from 128 fb^{-1} of proton-proton collisions at 13 TeV.
• Employed a data scouting technique to efficiently record low-momentum jet events.
• Analyzed fully hadronic final states for multijet signatures.

Main Results:

• Presented the first search for prompt hadronically decaying mass-degenerate higgsinos.
• Extended existing exclusion limits on RPV top squarks and gluinos.
• Probed electroweak production of RPV SUSY particles in hadronic final states for the first time.

Conclusions:

• The search provides new constraints on RPV SUSY models.
• The data scouting technique proved effective for multijet final states.
• This study opens new avenues for exploring RPV SUSY scenarios.
