Mean values and differential distributions of event-shape variables have been studied in neutral current deep inelastic scattering using an integrated luminosity of 82.2 pb collected with the ZEUS detector at HERA. The kinematic range is 80 < Q < 20 480GeV and 0.0024 < x < 0.6, where Q is the virtuality of the exchanged boson and x is the Bjorken variable. The data are compared with a model bas...
A search for single-top production, ep → etX, has been made with the ZEUS detector at HERA using an integrated luminosity of 130.1 pb. Events from both the leptonic and hadronic decay channels of the W boson resulting from the decay of the top quark were sought. For the leptonic mode, the search was made for events with isolated high-energy leptons and significant missing transverse momentum. F...
Cross sections for ep charged current deep inelastic scattering have been measured at a centre-of-mass energy of 318GeV with an integrated luminosity of 16.4 pb using the ZEUS detector at HERA. Differential cross-sections dσ/dQ, dσ/dx and dσ/dy are presented for Q > 200GeV. In addition, dσ/dxdQ was measured in the kinematic range 280GeV < Q < 30 000GeV and 0.015 < x < 0.42. The predictions of t...
Searches in ep collisions for heavy excited fermions have been performed with the ZEUS detector at HERA. Excited states of electrons and quarks have been searched for in ep collisions at a centre-of-mass energy of 300GeV using an integrated luminosity of 47.7 pb. Excited electrons have been sought via the decays e → eγ, e → eZ and e → νW . Excited quarks have been sought via the decays q → qγ a...
Bose-Einstein correlations in one and two dimensions have been studied in deep inelastic ep scattering events measured with the ZEUS detector at HERA using an integrated luminosity of 121 pb. The correlations are independent of the virtuality of the exchanged photon, Q, in the range 0.1 < Q < 8000GeV. There is no significant difference between the correlations in the current and target regions ...
Dijet production has been studied in neutral current deep inelastic ep scattering for 470 < Q < 20000 GeV with the ZEUS detector at HERA using an integrated luminosity of 38.4 pb. Dijet differential cross sections are presented in a kinematic region where both theoretical and experimental uncertainties are small. Next-to-leading-order (NLO) QCD calculations describe the measured differential cr...
The ability to anticipate the population-wide response of a target audience to a new movie or TV series, before its release, is critical to the film industry. Equally important is the ability to understand the underlying factors that drive or characterize viewer's decision to watch a movie. Traditional approaches (which involve pilot test-screenings, questionnaires, and focus groups) have reach...
Inclusive dijet and trijet production in deep inelastic ep scattering has been measured for 10 < Q < 100 GeV and low Bjorken x, 10 < xBj < 10 . The data were taken at the HERA ep collider with centre-of-mass energy √ s = 318GeV using the ZEUS detector and correspond to an integrated luminosity of 82 pb. Jets were identified in the hadronic centre-of-mass (HCM) frame using the kT cluster algorit...
Inclusive φ(1020)-meson production in neutral current deep inelastic ep scattering has been measured with the ZEUS detector at HERA using an integrated luminosity of 45 pb. The φ mesons were studied in the range 10 < Q < 100 GeV, where Q is the virtuality of the exchanged photon, and in restricted kinematic regions in the transverse momentum, pT , pseudorapidity, η, and the scaled momentum in t...
