Measurement of Mutual Coulomb Dissociation in $\sqrt{s_{NN}}=130$ GeV Au+Au collisions at RHIC

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/207986We report on the first measurement of Mutual Coulomb Dissociation in heavy ion collisions. We employ forward calorimeters to measure neutron multiplicity at beam rapidity in peripheral collisions. The cross-section for simultaneous electromagnetic breakup of Au nuclei at $\sqrt{s_{NN}}=130$ GeV is $σ_{MCD}=3.67\pm 0.25$ barns in good agreement with calculations.This paper has been submitted for publication in Phys.
