TL;DR: In this article, the authors compared the NLO QCD predictions with Monte Carlo (MC) models which incorporate leading-order matrix elements followed by parton showers and hadronisation.

TL;DR: In this article, a search for excited neutrinos decaying via ν ∗ →νγ, ǫ ∆ →νZ and à à →eW is presented using e−p collisions at 318-GeV centre-of-mass energy, corresponding to an integrated luminosity of 16.7-pb−1.

TL;DR: In this article, a search is performed for neutral non-standard-model Higgs bosons decaying to two muons in the context of the minimal supersymmetric standard model (MSSM).

TL;DR: In this paper, the photoproduction of prompt photons, together with an accompanying jet, has been studied in ep collisions at a center-of-mass energy of 318-GeV with the ZEUS detector at HERA using an integrated luminosity of 77-pb-1, and the differential γ+jet cross sections were reconstructed as functions of the transverse energy, pseudorapidity and xγ + obs, the fraction of the incoming photon momentum taken by the photon-jet system.
