The ATLAS Collaboration has made a significant advancement in the understanding of the Higgs boson by investigating its production in association with W or Z bosons (known as “VH production”), where the Higgs boson decays to bottom quarks. For the first time, LHC researchers have studied VH production in a fully hadronic final state.

Researchers at the ATLAS Experiment release the first-ever direct search for new composite dark particles called dark mesons, presented this week at the Large Hadron Collider Physics (LHCP) Conference in Boston.

In a new analysis from the ATLAS Collaboration, physicists merged five di-Higgs studies of LHC Run 2 data. By combining the power of all these decay channels, researchers achieved the most sensitive probe of di-Higgs production and the Higgs self-coupling.

In a new study submitted to Physical Review Letters, ATLAS scientists used a new algorithm to search for long-lived particles (LLP) produced in the decay of Higgs bosons. These LLPs may leave a distinct signature of one or more hadronic “jets” of particles originating at a significantly displaced position from the proton–proton collision point.

The twelfth annual conference on Large Hadron Collider physics (LHCP 2024) kicks off today in Boston, USA. This week-long event will feature a detailed review of the latest experimental and theoretical results in collider physics, including several final studies of the LHC Run-2 dataset (collected in 2015-2018) and discussions on future research directions for the high-energy particle-physics community.
