Annotation	A precision measurement of jet cross sections in neutral current deep-inelastic scattering for photon virtualities 5.5 < Q2 < 80 GeV2 and inelasticities 0.2 < y < 0.6 is presented, using data taken with the H1 detector at HERA, corresponding to an integrated luminosity of 290 pb−1. Double-differential inclusive jet, dijet and trijet cross sections are measured simultaneously and are presented as a function of jet transverse momentum observables and as a function of Q2. The data are compared to predictions from perturbative QCD in next-to-leading order in the strong coupling, in approximate next-to-next-to-leading order and in full next-to-nextto- leading order.Using also the recently published H1 jet data at high values of Q2, the strong coupling constant αs (MZ ) is determined in next-to-leading order.
