Dijet angular distributions of photoproduction events in which a D * ± meson is produced in association with one of two energetic jets have been measured with the ZEUS detector at HERA, using an integrated luminosity of 120 pb −1. Differential cross sections as a function of the angle between the charm-jet and the proton-beam direction in the dijet rest(More)

First measurements of cross sections for isolated prompt photon production in deep inelastic ep scattering have been made using the ZEUS detector at the HERA electron-proton collider using an integrated luminosity of 121 pb −1. A signal for isolated photons in the transverse energy and rapidity ranges 5 < E γ T < 10 GeV and −0.7 < η γ < 0.9 was observed for(More)
Isolated myenteric ganglion networks were used in a perifusion protocol to characterize the response of interstitial adenosine levels to changes in prevailing PO2. The biological activity of such adenosine was assessed using inhibition of release of substance P (SP) as a functional measure of adenosine activity, and the effect of altered O2 tension on both(More)

A search for narrow-width resonances that decay into electron+jet or neu-trino+jet has been performed with the ZEUS detector at HERA operating at center-of-mass energies of 300 and 318 GeV. An integrated e + p luminosity of 114.8 pb −1 and e − p luminosity of 16.7 pb −1 were used. No evidence for any resonance was found. Limits were derived on the Yukawa(More)
A search for QCD-instanton-induced events in deep inelastic ep scattering has been performed with the ZEUS detector at the HERA collider, using data corresponding to an integrated luminosity of 38 pb −1. A kinematic range defined by cuts on the photon virtuality, Q 2 > 120 GeV 2 , and on the Bjorken scaling variable , x > 10 −3 , has been investigated. The(More)

Inclusive event-shape variables have been measured in the current region of the Breit frame for neutral current deep inelastic ep scattering using an integrated luminosity of 45.0 pb −1 collected with the ZEUS detector at HERA. The variables studied included thrust, jet broadening and invariant jet mass. The kinematic range covered was 10 < Q 2 < 20 480 GeV(More)

Diffractive production of D * ± (2010) mesons in deep inelastic scattering has been measured with the ZEUS detector at HERA using an integrated luminosity of 44.3 pb −1. Diffractive charm production is identified by the presence of a large rapidity gap in the final state of events in which a D * ± (2010) meson is reconstructed in the decay channel D * + →(More)
