Contribution

The study introduces a light front quark-diquark model to predict azimuthal spin asymmetries, including for future electron-ion collider experiments, expanding on previous phenomenological approaches.

Findings

Model predictions agree with existing HERMES and COMPASS data.

Analysis of T-even TMDs in semi-inclusive deep inelastic scattering.

Abstract

We have presented the results for the single and double spin asymmetries in semi-inclusive deep inelastic scatterings for proton in a light front quark-diquark model. The asymmetries generated by the T-even TMDs are discussed here. The model predictions are found to agree with the available data. We also present our model predictions for the Collins asymmetry for the future electron-ion collider experiments.
