Transverse single-spin asymmetries of pion production in semi-inclusive DIS at subleading twist
Transverse single-spin asymmetries of pion production in semi-inclusive DIS at subleading twist
We study the single-spin asymmetries with the $\mathrm{sin}{\ensuremath{\phi}}_{S}$ and $\mathrm{sin}(2{\ensuremath{\phi}}_{h}\ensuremath{-}{\ensuremath{\phi}}_{S})$ angular dependences for charged and neutral pions produced in semi-inclusive deep inelastic scattering on the transversely polarized proton target. The theoretical interpretations of the two asymmetries are presented in terms of the convolution of the twist-3 quark transverse momentum dependent …
