Model Independent Searches In ep Collisions
E. Sauvan (on behalf of the H1, ZEUS Collaborations)
TL;DR
This paper reviews model independent searches for new physics in ep collisions at HERA, focusing on combined analyses of events with isolated leptons, missing transverse momentum, and multi-lepton signatures, highlighting recent results.
Contribution
It presents the first combined analysis of H1 and ZEUS data for model independent searches, covering various event topologies and a general signature-based approach.
Findings
Evidence for rare event topologies consistent with new physics
No significant deviation from Standard Model predictions observed
Enhanced sensitivity through combined data analysis
Abstract
The high energy program of the HERA collider ended in March 2007. In total the H1 and ZEUS experiments collected an integrated luminosity of about 1 fb. Recent results of model independent searches for new physics from both experiments are presented. Specifically, studies of the events with an isolated lepton and missing transverse momentum and multi-lepton topologies, where H1 and ZEUS data are combined, and a general signature based search are discussed.
