We report on a search for magnetic monopoles (MMs) produced in ultraperipheral Pb-Pb collisions during Run 1 of the LHC. The beam pipe surrounding the interaction region of the CMS experiment was exposed to 184.07 μb^{-1} of Pb-Pb collisions at 2.

Adapting effective, evidence-based interventions to a new context is a resource-saving strategy. In Canada, the D-PRESCRIBE intervention comprised a patient educational brochure and a pharmaceutical opinion inviting physicians to revise BZRA prescribing and consider safer alternatives.

In this sense, we use of the vacuum cross sections for the Drell-Yan reactions derived within the mentioned framework to evaluate the cross section averaged over the thermal distribution associated to other particles that constitute the hot medium where the monopoles propagate.

By electromagnetic duality, a sufficiently strong magnetic field would similarly produce magnetic monopoles, if they exist. Magnetic monopoles are hypothetical fundamental particles that are predicted by several theories beyond the standard model but have never been experimentally detected.
