Multi-jet cross sections in charged current e+-p scattering at HERA

Understand

Jet cross sections were measured in charged current deep inelastic e+-p scattering at high boson virtualities Q^2 with the ZEUS detector at HERA II using an integrated luminosity of 0.36 fb^-1.

• Differential cross sections are presented for inclusive-jet production as functions of Q^2, Bjorken x and the jet transverse energy and pseudorapidity.
• The dijet invariant mass cross section is also presented.
• Observation of three- and four-jet events in charged-current e+-p processes is reported for the first time.
