When compared to lower energy data at similar 2 , the ...

Measurements of the cross sections for charged current deep inelastic scattering in e − p collisi... more Measurements of the cross sections for charged current deep inelastic scattering in e − p collisions with longitudinally polarised electron beams are presented. The measurements are based on a data sample with an integrated luminosity of 175 pb−1 collected with the ZEUS detector at HERA at a centre-of-mass energy of 318 GeV. The total cross section is given for positively and negatively polarised electron beams. The differential cross-sections d σ/dQ 2, d σ/dx and d σ/dy are presented for Q 2>200 GeV2. The double-differential cross-section d 2 σ/dxdQ 2 is presented in the kinematic range 280Q 22 and 0.015x

The data sample was collected during 1988-1989 at the Fermilab Tevatron Collider and has an integrated luminosity of 4.1 pb -1 . We have extended our previous search for eμ final states to ...

The study ...

The J/ψ was detected in its e + e − and μ + μ − decay modes. The photoproduction cross ...
