Flavor, transverse momentum, and azimuthal dependence of charged pion multiplicities in SIDIS with 10.6 GeV electrons
This paper reports high-precision measurements of charged pion multiplicities and their azimuthal modulations in semi-inclusive deep inelastic scattering off proton and deuteron targets using a 10.6 GeV electron beam at Jefferson Lab, revealing consistent transverse momentum dependencies and significant π− azimuthal asymmetries that will enable improved determinations of quark transverse momentum distributions.
