Search for contact interactions in deep inelastic e⁺p → e⁺X scattering at HERA

European Physical Journal C 14:2 (2000) 239-254

Authors:

Abstract:

In a search for signatures of physics processes beyond the Standard Model, various eeqq vector contact-interaction hypotheses have been tested using the high-Q2 deep inelastic neutral-current e+p scattering data collected with the ZEUS detector at HERA. The data correspond to an integrated luminosity of 47.7pb-1 of e+p interactions at 300 GeV center-of-mass energy. No significant evidence of a contact-interaction signal has been found. Limits at the 95% confidence level are set on the contact-interaction amplitudes. The effective mass scales Λ corresponding to these limits range from 1.7 TeV to 5 TeV for the contact-interaction scenarios considered.

Search for resonances decaying to e+-jet in e+p interactions at HERA

European Physical Journal C 16:2 (2000) 253-267

Authors:

Abstract:

The e⁺-jet invariant mass spectrum produced in the reaction e⁺p → e⁺ X has been studied at a center-of-mass energy of 300 GeV. The data were collected using the ZEUS detector operating at the HERA collider, and correspond to an integrated luminosity of 47.7 pb^-1. The observed mass spectrum is in good agreement with Standard Model expectations up to an e⁺-jet mass of 210 GeV. Above this mass, some excess is seen. The angular distribution of these events is typical of high-Q² neutral current events and does not give convincing evidence for the presence of a narrow scalar or vector state. Limits are presented on the product of cross section and branching ratio for such a state and are interpreted as limits on leptoquark or R-parity-violating squark production. Specific leptoquark types are ruled out at 95% confidence level for coupling strength λ = 0.3 for masses between 150 and 280 GeV.
