Transverse single-spin asymmetries in ${\hat{I}}^3$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 (${\hat{I}}^3$SIDIS), $A_{UT}^{{\hat{I}}^3\mathrm{SIDIS}}$, provide an unprecedented opportunity t…
