Description

Multijet production rates in neutral current deep inelastic scattering have been measured in the range of exchanged boson virtualities 105 GeV and -1<ηjetLAB<2.5. Next-to-leading-order QCD calculations describe the data well. The value of the strong coupling constant αs(MZ), determined from the ratio of the trijet to dijet cross sections, is αs(MZ)=0.1179±0.0013(stat.)+0.0028-0.0046(exp.)+0.0064-0.0046(th.). (orig.)
