Transverse single-spin asymmetries in $\gamma$SIDIS as a direct probe of quark-gluon-quark longitudinal momentum structure

Michael Harris, Jacob Marsh, Daniel Pitonyak +4

Transverse single-spin asymmetries in the semi-inclusive deep-inelastic production of isolated photons ($\gamma$SIDIS), $A_{UT}^{\gamma \mathrm{SIDIS}}$, provide an unprecedented opportunity to…
