High Energy Physics

High energy physics involves the study of the fundamental building blocks of nature at the shortest distances. These are the fundamental particles that are described by quantum fields such as the Higgs field found at CERN's Large Hadron Collider (LHC). Our group studies theories beyond the Standard Model of particle physics both from theoretical and phenomenological perspectives.

A no-go theorem for exotic alternatives to black holes as LIGO/Virgo sources

Five of the ground-breaking gravitational wave detections by the LIGO/Virgo collaboration have been interpreted as black hole collisions forming a more massive black hole. It is hard to demonstrate conclusively that these objects are indeed black holes, and there is a lively debate on the intriguing possibility that other, more exotic alternatives could explain the observations. In an article to appear in Physical Review Letters, Gr@v members P.

Abstract: The hierarchy problem and the irreconcilability of quantum mechanics and general relativity are two of the most frustrating problems that the Standard Model fails to solve. The existence of extra dimensions, however, would provide the much awaited solutions. If extra dimensions exist and push the Planck scale down to the TeV range, signatures of extra dimensions could be found at the Large Hadron Collider in Geneva, Switzerland. Results of TeV-scale gravity searches with the ATLAS and CMS detectors at 13 TeV are summarized, and outlook is provided on the best way forward in the absence of discoveries.
