{"arxiv_id":"0909.2862","title":"Dark Force Detection in Low Energy e-p Collisions","abstract":"We study the prospects for detecting a light boson X with mass m_X < 100 MeV at a low energy electron-proton collider. We focus on the case where X dominantly decays to e+ e- as motivated by recent \"dark force\" models. In order to evade direct and indirect constraints, X must have small couplings to the standard model (alpha_X < 10^-8) and a sufficiently large mass (m_X >10 MeV). By comparing the signal and background cross sections for the e- p e+ e- final state, we conclude that dark force detection requires an integrated luminosity of around 1 inverse attobarn, achievable with a forthcoming JLab proposal.","primary_cat":"hep-ph","cross_cats":["hep-ex","nucl-ex"],"submitted_at":"2009-09-16T06:47:56+00:00","latest_version":2,"source":"arxiv","source_label":"arXiv","source_url":null,"has_pdf":true,"has_source":false,"verdict":"CONDITIONAL","confidence":"HIGH","one_line_summary":"Low-energy electron-proton collisions at the JLab FEL could probe dark-force bosons with masses of 10 to 100 MeV and couplings near 10^-8, given about 1 inverse attobarn of integrated luminosity.","novelty_score":5.0,"correctness_risk":"low","formal_verification":"none","upvotes":0,"downvotes":0,"pith_score":0,"inbound_count":45,"_links":{"html":"https://pith.science/paper/0909.2862","verdict":"/api/v1/verdicts/0909.2862"}}
