AbstractA precision measurement of jet cross sections in neutral current deep-inelastic scattering for photon virtualities$$5.5<Q^2 <80\,\mathrm {GeV}^2 $$5.5<Q2<80GeV2and inelasticities$$0.2<y<0.6$$0.2<y<0.6is presented, using data taken with the H1 detector at HERA, corresponding to an integrated luminosity of$$290\,\mathrm {pb}^{-1}$$290pb-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$$Q^2$$Q2. Jet cross sections normalised to the inclusive neutral current DIS cross section in the respective$$Q^2$$Q2-interval are also determined. Previous results of inclusive jet cross sections in the range$$150<Q^2 <15{,}000\,\mathrm {GeV}^2 $$150<Q2<15,000GeV2are extended to low transverse jet momenta$$5<P_\mathrm{T}^\mathrm{jet} <7\,\mathrm {GeV} $$5<PTjet<7GeV. 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-next-to-leading order. Using also the recently published H1 jet data at high values of$$Q^2$$Q2, the strong coupling constant$$\alpha _s(M_Z)$$αs(MZ)is determined in next-to-leading order.
