چکیده

We compute the two-loop enhancement factors for our earlier one-loop calculations of leading (1=Q) power corrections to the mean values of some event shape variables in deep inelastic lepton scattering. The enhancement is found to be equal to the universal \Milan factor" for those shape variables considered, provided the one-loop calculation is performed in a particular way. As a result, the phenomenology of power corrections to DIS event shapes remains largely una ected.

Power Corrections to Event Shapes in Deep Inelastic Scattering ∗

We investigate the power-suppressed corrections to the mean values of various quantities that characterise the shapes of final states in deep inelastic lepton scattering. Our method is based on an analysis of one-loop Feynman graphs containing a massive gluon, which is equivalent to the evaluation of leading infrared renormalon contributions. As in e + e − annihilation, we find that the leading...

Event shapes in deep inelastic ep → eX scattering at HERA ZEUS

5-0290 Session: QCD Hard Interactions Event shapes in deep inelastic ep → eX scattering at HERA Abstract Means and differential distributions of event-shape variables have been studied in neutral current deep inelastic scattering using an integrated luminosity of 82.2pb −1 collected with the ZEUS detector at HERA. The kinematic range used was 80 < Q 2 < 20480 GeV 2 and 0.0024 < x < 0.6, where Q...

Power Corrections in Deep Inelastic Event Shape Variables

Results are presented for the leading power-suppressed (1/Q) contributions to shape variables in deep inelastic lepton scattering. These are then combined with available leading order perturbative estimates. INTRODUCTION The increasing quantity of data from HERA has given a great boost to the testing of QCD via determinations of the strong coupling constant and the possibility of observing, ove...

JET SHAPES AND DETERMINATIONS OF s FROM HADRONIC FINAL STATES IN DEEP INELASTIC SCATTERING AT HERA

Recent results from the study of hadronic nal states in deep inelastic scattering at HERA are reviewed. Jet shapes from neutral and charged current interactions at HERA are compared to those from e + e ? annihilation and p p collisions. The (2+1) jet event rate distributions R2+1(Q 2) and y2 are measured using the modiied JADE jet algorithm. The value of the strong coupling constant s is determ...
