Description
In the aftermath of a high energy non-central heavy-ion collision, it is expected that along a quark-gluon plasma (QGP) a very strong electromagnetic field is produced. To characterize the strength of such a field, it has been theorized that it can induce measurable effects on the width and leptonic invariant mass of the Z-boson, with the effect being maximal for semi-central collisions. We present the status of an ongoing study of the relative change of the mass and width with centrality of the Z boson, from Pb-Pb collisions at √sNN=5.02 TeV, using the CMS detector.
