Abstract
The shapes of jets with transverse energies, E-T(jet), up to 45 GeV produce d in neutral- and charged-current deep inelastic e(+)p scattering (DIS) at Q(2) > 100 GeV2 have been measured with the ZEUS detector at HERA. Jets are identified using a cane algorithm in the eta-phi plane with a cone radius of one unit. The jets become narrower as E-T(jet) increases. The jet, shape s in neutral- and charged-current DIS are found to be very similar. The jet s in neutral-current DIS are narrower than those in resolved processes in p hotoproduction and closer to those in direct-photon processes for the same ranges in E-T(jet) and jet pseudorapidity. The jet shapes in DIS are observ ed to be similar to those in e(+)e(-) interactions and narrower than those in (p) over bar p collisions for comparable E-T(jet). Since the jets in e()e(-) interactions and e(+)p DIS are predominantly quark initiated in both cases, the similarity in the jet shapes indicates that the pattern of QCD r adiation within a quark jet is to a large extent independent of the hard sc attering process in these reactions.
