Abstract We propose a new observable for the measurement of the forward–backward asymmetry $$(A_{FB})$$ ( A FB ) in Drell–Yan lepton production. At hadron colliders, the $$A_{FB}$$ A FB distribution is sensitive to both the electroweak (EW) funda

Difference between the u¯ and d¯ sea quark distributions in the proton was first observed in the violation of the Gottfried sum rule in deep-inelastic scattering (DIS) experiments. The parton momentum fraction x dependence of this difference has be

Lepton scattering is an established ideal tool for studying inner structure of small particles such as nucleons as well as nuclei. As a future high energy nuclear physics project, an Electron-ion collider in China (EicC) has been proposed. It will be

Factorization of the forward-backward asymmetry and measurements of the weak mixing angle and proton structure at hadron colliders

Publikováno v: Physical Review

The forward-backward charge asymmetry (AFB) at hadron colliders is sensitive to both the electroweak (EW) symmetry breaking represented by the effective weak mixing angle sin2θeffℓ, and the proton structure information in the initial state modeled
