Coherent diffractive photoproduction of ${\rho }^0$ mesons on gold nuclei at RHIC

STAR Collaboration, L. Adamczyk, J. K. Adkins +342

The STAR Collaboration reports on the photoproduction of ${\pi }^{+}{\pi }^{-}$ pairs in gold-gold collisions at a center-of-mass energy of 200 GeV/nucleon-pair. These pion pairs are produced wh…
