Observation of pi+pi-pi+pi- photoproduction in ultraperipheral heavy-ion collisions at [sqrt]sNN=200 GeV at the STAR detector
We present a measurement of pi+pi-pi+pi-photonuclear production in ultraperipheral Au-Au collisions at [sqrt]sNN=200 GeV from the STAR experiment. The pi+pi-pi+pi- final states are observed at low transverse momentum and are accompanied by mutual nuclear excitation of the beam particles. The strong...
