Recent Photoproduction Results From ZEUS
Recent results for inclusive jet cross sections, dijet cross sections and dijet angular distributions are compared with NLO perturbative QCD calculations. The observation of isolated high PT photons (prompt photons) is also reported. INTRODUCTION Collisions of 27.5 GeV positrons with 820 GeV protons at HERA are studied using the ZEUS detector. The processes of interest here are those where an a...
متن کاملRecent Results from ZEUS 3
A summary of recent results from ZEUS is presented. New ZEUS results from HERA-1 data include Structure Functions, QCD fits, analysis of hadronic final states, precision measurements of αs, production of heavy flavor mesons and baryons and studies of diffraction. Results from the new HERA-II running include the measurement of the cross section for polarized charged current events and charm even...
متن کاملQCD fits to ZEUS and fixed target structure function data
Preliminary results are presented on the gluon density at low x obtained from a QCD analysis of ZEUS 1994 F 2 structure function data combined with those from NMC. Also given are estimates of the experimental error on the e + p NC Born cross section at large x and Q 2. This estimate is obtained from propagation of the statistical and systematic errors on fixed target structure functions.
متن کاملStructure function results from H 1
New structure function results from H1 are presented. The measurements cover a huge kinematical range for Q, the four momentum transfer squared, from 0.35GeV to 30 000GeV, and for Bjorken x between ∼ 5 · 10 and 0.65. At Q > 100GeV, full HERA I data have been analyzed. The data are compared with a new QCD analysis. The impact of the HERA I data on the parton density functions is discussed. azhan...
متن کاملMeasurement and Phenomenology of the Proton Structure Function F2 from Zeus at Hera
Measurements of the proton structure function F2 in the Q range 0.6 − 17 GeV from ZEUS 1995 shifted vertex data and Q ≃ 1.5 − 20000 GeV from 1996 and 1997 ZEUS data are presented. From the former and other ZEUS F2 data the slopes dF2/d lnQ at fixed x and dF2/d ln(1/x) at fixed Q are derived. F2 data at Q below 0.9 GeV are described successfully by a combination of generalised vector meson domin...
