CMS Rules Out Some Quantum Black Holes at 10^-20 Meters, Broadening Hunt for New Particles

Summary
CMS found no sign of microscopic quantum black holes in Large Hadron Collider data, excluding models with specific properties within the energy range it tested.
The search used a new supervised analysis that sums decay-product energy and looks for highly spherical events, a method researchers say can be reused to spot other beyond-Standard-Model particles.
Those limits target theories with extra spatial dimensions that try to explain the gap between the observed energy scale of the universe and the much higher Planck scale.
By probing proton collisions down to about 10^-20 meters, the result narrows where new physics could still hide and helps steer future theory work and CERN searches.
