Next-to-Leading Order Hard Scattering Using Fully Unintegrated Parton Distribution Functions

, 2008
We calculate the next-to-leading order fully unintegrated hard scattering coefficient for unpolarized gluon-induced deep inelastic scattering using the logical framework of parton correlation functions developed in previous work.

Neutron spin structure from polarized deuteron DIS with proton tagging

Physics Letters B, 2019
Polarized electron-deuteron deep-inelastic scattering (DIS) with detection of the spectator proton (“tagged DIS”) enables measurements of neutron spin structure with maximal control of nuclear effects.

Flavor distributions in the nucleons: SU(2) sea asymmetry or isospin symmetry breaking? [PDF]

, 2006
The Gottfried sum-rule violation reported by the New Muon Collaboration was interpreted as an indication for a flavor asymmetry of the sea quark in the nucleon.

NNLO contributions to inclusive-jet production in DIS and determination of \alpha_s

, 2015
We present the first calculation of inclusive jet production in deep-inelastic scattering with approximate next-to-next-to-leading order (aNNLO) contributions, obtained from a unified threshold resummation formalism. The leading coefficients are computed

Transverse momentum dependent distributions in e + e − and semi-inclusive deep-inelastic scattering using jets

Journal of High Energy Physics, 2019
The extraction of transverse momentum dependent distributions (TMDs) in semi-inclusive deep inelastic scattering (SIDIS) is complicated by the presence of both initial- and final-state nonperturbative physics.

Determination of pion and kaon fragmentation functions including spin asymmetries data in a global analysis

, 2013
We present new functional form of pion and kaon fragmentation functions up to next-to-leading order obtained through a global fit to single-inclusive electron-positron annihilation data and also employ, the semi-inclusive deep inelastic scattering ...
