TL;DR: In this article, a new set of leading twist parton distribution functions, referred to as "CJ15", is presented, which take advantage of developments in the theoretical treatment of nuclear corrections as well as new data.
Abstract: Here, we present a new set of leading twist parton distribution functions, referred to as "CJ15", which take advantage of developments in the theoretical treatment of nuclear corrections as well as new data. The analysis includes for the first time data on the free neutron structure function from Jefferson Lab, and new high-precision charged lepton and W-boson asymmetry data from Fermilab, which significantly reduce the uncertainty on the d/u ratio at large values of x.

TL;DR: In this paper, generalized parton distributions (GPDs), accessible in hard exclusive processes, carry information about the spatial distribution of forces experienced by quarks and gluons inside hadrons.

TL;DR: In this article, a set of factorization formulas for spin-dependent DIS and Drell-Yan cross sections at low transverse momentum is presented, which can be used to extract transversemomentum dependent parton distribution and fragmentation functions from relevant experimental data.

TL;DR: In this article, a Monte Carlo event generator simulating neutral and charged current ep interactions at HERA energies and beyond is described, and the present version 4.0 of the generator optionally treats the ep scattering either by means of structure-function parametrizations or on the basis of parton distribution functions in the framework of the quark-parton model.

TL;DR: The photon-photon collisions are investigated in the framework of the two-component dual parton model and the model is shown to agree well with hadron production data from hadron-hadron and photon- hadron collisions.
Abstract: Photon-photon collisions are investigated in the framework of the two-component dual parton model. The model contains contributions from direct, resolved soft, and resolved hard interactions. All free parameters of the model are determined in fits to hadron-hadron and photon-hadron cross section data. The model is shown to agree well with hadron production data from hadron-hadron and photon-hadron collisions. The multiparticle production in hadron-hadron, photon-hadron, and photon-photon collisions as predicted by the model is compared. Strong differences are only found as a function of the transverse momentum variable. The hadron production in photon-photon collisions at present and future electron-positron colliders is studied using photon spectra according to bremsstrahlung, beamstrahlung, and backscattered laser radiation.
