Exclusive production of 0 and J== mesons in e + p collisions has been studied with the ZEUS detector in the kinematic range 0:25 < Q 2 < 50 GeV 2 , 20 < W < 167 GeV for the 0 data and 2 < Q 2 < 40 GeV 2 , 50 < W < 150 GeV for the J== data. Cross sections for exclusive 0 and J== production have been measured as a function of Q 2 , W and t. The spin-density(More)
The dependence of dijet production on the virtuality of the exchanged photon, Q 2 , has been studied by measuring dijet cross sections in the range 0 < ∼ Q 2 < 2000 GeV 2 with the ZEUS detector at HERA using an integrated luminosity of 38.6 pb −1. Dijet cross sections were measured for jets with transverse energy E jet T > 7.5 and 6.5 GeV and(More)
The ZEUS detector has been used to study dissociation of virtual photons in events with a leading proton, γ ⋆ p → Xp, in e + p collisions at HERA. The data cover photon virtualities in two ranges, 0.03 < Q 2 < 0.60 GeV 2 and 2 < Q 2 < 100 GeV 2 , with M X > 1.5 GeV, where M X is the mass of the hadronic final state, X. Events were required to have a leading(More)
The e + p neutral-current deep inelastic scattering diierential cross-sections dd=dQ 2 , for Q 2 > 400 GeV 2 , dd=dx and dd=dy, for Q 2 > 400, 2500 and 10000 GeV 2 , have been measured with the ZEUS detector at HERA. The data sample of 47.7 pb ?1 was collected at a center-of-mass energy of 300 GeV. The cross-section, dd=dQ 2 , falls by six orders of(More)
The main object of this paper is to introduce and study a new concept of f-Wijsman lacunary statistical convergence of sequences of sets, where f is an unbounded modulus. The definition of Wijsman lacunary strong convergence of sequences of sets is extended to a definition of Wijsman lacunary strong convergence with respect to a modulus for sequences of(More)
