✦ Synopsis

We report measurements for coherent p" production, AuAu + AuAup', and coherent p" and efe-pair production accompanied by mutual nuclear Coulomb excitation, AuAu -+ Au*Au*p' and AuAu ---f Au*Au* + e+e-, in ultra-peripheral relativistic gold-gold collisions (UPC). We discuss transverse momentum, mass, and rapidity distributions. The two photon-process of e+e-pair production is an important probe of strong field QED because
