چکیده

Deep-inelastic scattering data, taken with the H1 detector at HERA, are used to study the event shape variables thrust, jet broadening, jet mass, parameter and two kinds of differential two-jet rate. The data cover a large range of the four-momentum transfer , which is considered to be the relevant energy scale, between and . The dependences of the mean values are compared with second order calculations of perturbative QCD applying power law corrections proportional to to account for hadronization effects. The concept of power corrections is investigated by fitting simultaneously a nonperturbative parameter and the strong coupling constant . To be submitted to Eur. Phys. J. C C. Adloff , V.

Two-loop enhancement factor for 1=Q corrections to event shapes in deep inelastic scattering

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 ph...

Measurement of event shapes in deep inelastic scattering at HERA

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 < Q2 < 20 480GeV and 6 × 10−4 < x < 0.6, where Q2 is the ...
