Electromagnetic dissociation of nuclei: From LHC to NICA

Le résumé fourni par la source

In ultraperipheral collisions (UPC) of relativistic nuclei, the nuclear density distributions do not overlap, and the collision partners interact through Lorentz-contracted Coulomb fields. This leads to electromagnetic dissociation (EMD) of the nuclei induced by equivalent Weizsäcker–Williams photons. The RELDIS model was used to simulate the EMD of [Formula: see text]Bi and [Formula: see text]Xe beam nuclei in the MPD experiment at NICA, focusing on neutron and proton emissions in [Formula: see text]Bi–[Formula: see text]Bi and [Formula: see text]Xe–[Formula: see text]W collisions in collider and fixed target experiments, respectively. These simulations are crucial for understanding the potential contamination of detected hadronic events by EMD events. In addition, EMD of [Formula: see text]Xe in UPC with a CsI target at the BM@N experiment was modeled. A monoenergetic neutron beam resulting from EMD at the BM@N setup can be used for detector calibration and radiobiological research.
