Are the H 1 and ZEUS “ High Q 2 Anomalies ” Consistent with Each Other ?
Both ZEUS and H1 have recently reported an excess of events at high Q and high Bjorken–x. However, the x distributions differ considerably; moreover, H1 sees more events with lower luminosity. Taken separately, the x distributions and the number of observed events are consistent between the two experiments at the few percent level. However, when combined it becomes clear that the results of H1 ...

متن کاملDiffraction at H1 and Zeus
The H1 and Zeus collaborations have measured the inclusive diffractive DIS cross section ep→ eXp and these measurements are in good agreement within a normalisation uncertainty. Diffractive parton density functions (DPDFs) have been extracted from NLO QCD fits to these data and the predictions of these DPDFs compare well with measurements of diffractive dijets in DIS, proving the validity of th...
متن کاملComment on Z ′ ’ s and the H 1 and ZEUS High Q 2 Anomalies
We investigate the effects of extra neutral gauge bosons on the high Q region of the ep → eX cross section at √ s = 300 GeV. We found that the only models with electroweak strength coupling, typical of extended gauge theories, that give a better fit to the H1 and ZEUS high Q data than the standard model, are ruled out by existing data from the Tevatron. From general scaling arguments, using the...
