A semi-analytical x-space solution for parton evolution — Application to non-singlet and singlet DGLAP equation

Journal of High Energy Physics
We present a novel semi-analytical method for parton evolution. It is based on constructing a family of analytic functions spanning x-space which is closed under the considered evolution equation.

Angular distributions of Drell-Yan leptons in the TMD factorization approach

Journal of High Energy Physics
We present a comprehensive study of the angular structure functions for Drell-Yan leptons in Z/γ-boson production within the framework of the transverse momentum dependent (TMD) factorization theorem, including kinematic power corrections (KPCs). We find

T-even TMDs for the spin-0 pseudo-scalar mesons upto twist-4 using light-front formalism

Journal of High Energy Physics
We have investigated the pseudo-scalar meson structure in the form of transverse momentum-dependent parton distribution functions (TMDs) in the light-front based holographic model and quark model.

Parton distributions confront LHC Run II data: a quantitative appraisal

Journal of High Energy Physics
We present a systematic comparison of theoretical predictions and various high-precision experimental measurements, specifically of differential cross sections performed by the LHC run II for Drell-Yan gauge boson, top-quark pair, single-inclusive jet ...
