Charm hadrons were produced copiously in ep collisions with a centre-of-mass energy of 318GeV at HERA providing a means to study charm hadronisation. During first phase of the HERA operation (1992-2000), the ZEUS collaboration accumulated data sample corresponding to an integrated luminosity of ∼ 120 pb. Measurements of the D, D, D and Λc production a with the HERA I data were used to determine...

Inclusive production of K SK 0 S in ep collisions was studied with the ZEUS detector. Significant production of J = 2 tensor mesons and of the 0 glueball candidate f0(1710) was seen. Masses and widths were compared with previous experiments. The H1 Collaboration saw a charm pentaquark candidate in the D∗p spectrum at 3.1 GeV, which was not confirmed by a ZEUS higher statistics search. With the ...

Urology has continuously embraced novel technologies, such as shockwave lithotripsy, lasers, and laparoscopy, that reduce patient morbidity yet maintain an excellent standard of care. To potentially increase the clinical applicability of laparoscopy, robots that enhance operative performance have recently been introduced for a variety of laparoscopic procedures, such as laparoscopic radical pro...

There is an emerging consensus on the need to develop tool-kits for building distributed multi-agent systems. This paper outlines ZEUS, an advanced development tool-kit for constructing collaborative agent applications. ZEUS is a culmination of a careful synthesis of established agent technologies with the addition of some new ones, to provide an integrated environment for the rapid software en...

on behalf of the ZEUS and H1 Collaborations Inclusive photoproduction cross-sections of the neutral mesons η, ρ 0 , f 0 (980) and f 2 (1270) have been measured by H1 and compared to the photoproduction of π + in ep collisions at HERA. Also, inclusive K 0 s K 0 s production and evidence for a narrow baryonic state decaying to K 0 s p have been observed by ZEUS at HERA.

On behalf on the ZEUS Collaboration The energy dependence of exclusive vector meson (V) production is studied using the ZEUS data. The SU(4) universality of V cross sections in the Q 2 + M 2 V scale is tested. The energy dependence of the ratio of the cross sections for V production to the total γ * p cross section is compared with expectations based on pQCD and Regge approaches.

The ZEUS inclusive differential cross-section data from HERA-I, for charged and neutral current processes taken with e and e− beams, have been used in a new a NLO QCD analysis to extract the parton distribution functions (PDFs) of the proton within a single experiment. The precision of the high-x gluon determination is improved by using ZEUS differential cross-section data on inclusive jet prod...
