“…While highx, valence quarks seem to be confined at the center of the nucleon, low-x contributions seem to be spread at the periphery, resulting in a larger nucleon size once the low-x region is explored. A recent measurement by COMPASS on the 2012 pilot run has been reported, which extends the previous measurements by H1 and ZEUS [39,40,41] in the low-x region. Furthermore, the latest JLab data from Hall-A [42,43] and Hall-B [44] cover with unprecedented precision the high-x domain [45].…”

The working group on Spin Physics at the XXIV International Workshop on Deep-Inelastic Scattering and Related Subjects (DIS2016) witnessed a significant progress in the theoretical and experimental investigations aiming at unveiling the innermost structure of the proton. Results ranged from proton's one-dimensional representation to its multi-dimensional imaging. In this contribution, we summarize a selection of the topics discussed and of the results presented. For details, we refer to the individual contributions collected in the proceedings of this workshop.

Scaled momentum distributions for the strange hadrons K 0 S and Λ/Λ were measured in deep inelastic ep scattering with the ZEUS detector at HERA using an integrated luminosity of 330 pb −1 . The evolution of these distributions with the photon virtuality, Q 2 , was studied in the kinematic region 10 < Q 2 < 40000 GeV 2 and 0.001 < x < 0.75, where x is the Bjorken scaling variable. Clear scaling violations are observed. Predictions based on different approaches to fragmentation were compared to the measurements. Leading-logarithm parton-shower Monte Carlo calculations interfaced to the Lund string fragmentation model describe the data reasonably well in the whole range measured. Nextto-leading-order QCD calculations based on fragmentation functions, FFs, extracted from e + e − data alone, fail to describe the measurements. The calculations based on FFs extracted from a global analysis including e + e − , ep and pp data give an improved description. The measurements presented in this paper have the potential to further constrain the FFs of quarks, anti-quarks and gluons yielding K 0 S and Λ/Λ strange hadrons.

Inclusive jet and multijet cross sections measured in ep collisions in different kinematic regions by the H1 and ZEUS experiments are shown. The measurements are used to extract the strong coupling alpha_s as a function of the scale and at the mass of the Z-boson. Results from prompt photon production in comparison with pQCD calculations are shown in photoproduction and deep-inelastic scattering. Other topics address scaled momentum distributions of charged particles, a measurement of the transverse momenta of charged particles and the first measurement of the charge asymmetry at HERA.Comment: 4 pages,7 figure
