Description
We re-interpret the jet clustering as an axis-finding procedure which, along with the proton beam, defines the virtual photon transverse momentum $q_T$ in deep inelastic scattering (DIS). In this way, we are able to probe the nucleon intrinsic structures with jets in a fully inclusive manner, similar to the Drell-Yan process. We present the factorization formulae and a complete list of the leading-power azimuthal asymmetries in deep-inelastic scattering of a nucleon. We show that, within the winner-takes-all axis finding algorithm, couplings of the time-reversal-odd jet functions to the quark transversities and the Boer-Mulders functions could give rise to azimuthal asymmetries. We also give predictions for the azimuthal asymmetry of back-to-back dijet production in $e^+e^-$ annihilation.
