The Boer-Mulders and Cahn Effects: Azimuthal Modulations in the Spin-Independent Sidis Cross Section at Hermes
These measurement would not have been possible without an improved hadron-type identification algorithm for the Ring Imaging Cherenkov (RICH) detector. The EVT event-level algorithm is presented and now is the primary method used at Hermes.

The Boer-Mulders and Cahn effects: azimuthal modulations in the spin-independent SIDIS cross section at Hermes
The coφh and cos 2φh modulations of the spin independent semi-inclusive deep inelastic scattering cross section were measured at Hermes. These modulations are sensitive to the polarization and transverse motion of quarks within the nucleon. The Cahn effect, which contributes at subleading twist …

TMD Approach in High Energy Physics:Theory and Applications
… along two complementary directions: the study of azimuthal distributions of hadron pairs produced in photon–photon collisions, where we formulated the kinematics and helicity formalism and derived the pattern of azimuthal modulations proportional to the TMD fragmentation functions, and the use of …
