Abstract

Inclusive jet, dijet and trijet differential cross sections have been measured in neutral current deep-inelastic scattering for exchanged boson virtualities 150 < Q² < 15000 GeV² with the H1 detector at HERA using an integrated luminosity of 351 pb^-1. The multijet cross sections are presented as a function of Q², the transverse momentum of the jet P_T (the mean transverse momentum for dijets and trijets) and the proton's longitudinal momentum fraction of the parton participating in the hard interaction ξ. The cross sections are compared to perturbative QCD calculations at next-to-leading order and the value of the strong coupling α_s(M_Z) is determined.
