Preliminary findings from CERN’s Large Hadron Collider may have uncovered experimental evidence for physics beyond the Standard Model. Data from the CMS experiment is showing significant excesses of particles known as leptons being created in triplets, a result that could be interpreted as evidence for a theory called supersymmetry.

The findings, presented during a talk Oct. 19 at a conference dedicated to LHC searches for new physics, have piqued the interest of some members of the field.

“This is clearly something to watch closely over the coming months,” physicist Matt Strassler wrote on his...
