Gluon Sivers function and transverse single spin asymmetries in $e+p^{\uparrow }\to \gamma +X$

Siddhesh Padval, Rohini M. Godbole, Abhiram Kaushik +2

We present estimates of transverse single-spin asymmetry in prompt photon production in the scattering of low virtuality photons off a polarized proton target and discuss the possi…
