The ATLAS Collaboration reports the first evidence of Higgs-boson production at high transverse momentum in decays to a pair of bottom quarks.

At the 2026 Recontres de Moriond conferences, physicists from the ATLAS Collaboration presented new searches for additional sources of CP violation linked to the Higgs-boson interactions with W and Z bosons.

An invisible field fills the Universe, giving mass to fundamental particles and shaping the building blocks of matter – the Higgs field. The Higgs boson is its observable manifestation and a cornerstone of the Standard Model. By studying it with increasing precision, physicists are not only refining their understanding of the current theory but also searching for new phenomena that extend beyond it. Two new results from the ATLAS Collaboration push into this challenging territory, improving the sensitivity to Higgs-boson decays to bottom (H→bb) and charm quarks (H→cc).

Summary of new ATLAS results presented at the Rencontres de Moriond conferences 2026.

ATLAS sets new limits on the masses of supersymmetric higgsinos, surpassing results by the Large Electron–Positron (LEP) collider experiments over 20 years ago.

In a new result analysing the full LHC Run-2 dataset (collected 2015-2018), the ATLAS Collaboration studied a unique experimental signature known as "disappearing tracks".
