Higgs Boson Unveils New Discovery at Large Hadron Collider

Speedy Summary

• The ATLAS Collaboration presented findings at the 2025 European Physical society Conference on High Energy Physics (EPS-HEP) regarding rare Higgs-boson decays using data from Run 3 of the Large Hadron Collider (LHC).
• Two decay processes were studied:

– Higgs decay into muons (H→μμ): Very rare, occurring in just 1 out of every 5000 Higgs decays. Significance observed was 3.4 standard deviations, with a statistical fluctuation probability of less than one in 3000.
– Higgs decay into Z boson and photon (H→Zγ): Involves an intermediate loop of virtual particles. Observed significance reached a stringent level of sensitivity at 2.5 standard deviations.

• Data combined included Run-3 dataset (165 fb⁻¹ collected during 2022-2024) and Run-2 dataset (140 fb⁻¹ from years earlier), enabling researchers to refine methods like better background modelling and advanced event-selection techniques.
