The exotic particles that could finally break the Standard Model

Penguin decays from CERN's latest Large Hadron Collider experiment hint at weird new physics that could reshape our understanding of the fundamental forces of nature.

Physicists at CERN have observed anomalies in the decay patterns of B mesons that don't align with Standard Model predictions. These rare "penguin" decay processes, named for their Feynman diagram shape, suggest the existence of new particles or forces beyond what current theories can explain.

The findings, published in Nature Physics, represent the strongest evidence yet that the Standard Model — the theoretical framework describing fundamental particles and their interactions — may be incomplete.
