Existing g g , g A measurements @ RHIC

• Measured processes in A+A UPC collisions:

• STAR:

• (1) Coherent rproduction: g+A ®A*+ r(®p+p-)

• (2) Dielectron continuum at low minv : g +g ®(A*) + e+e–

• PHENIX (Preliminary):

• (1) Coherent J/production: g+A ®A*+ J/(®e+e–)

• (2) Dielectron continuum at high minv : g+g ®(A*) + e+e–
