Abstract:
The shapes of jets with transverse energies, E(T)(jet), up to 45 GeV produced in neutral- and charged-current deep inelastic e(+)p scattering (DIS) at Q(2) > 100 GeV(2) 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, shapes in neutral- and charged-current DIS are found to be very similar. The jets in neutral-current DIS are narrower than those in resolved processes in photoproduction 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 observed 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 radiation within a quark jet is to a large extent independent of the hard scattering process in these reactions.
