ATLAS and CMS observe simultaneous production of four top quarks

March 28, 2023

The ATLAS and CMS collaborations have observed the simultaneous production of four top quarks, the heaviest elementary particle, in collisions at the world's largest particle accelerator, located at CERN. The Institut de Física d'Altes Energies (IFAE) plays a prominent role in the observation of this rare phenomenon that could be key to searching for new particles beyond the Standard Model.

The Higgs boson, ten years after its discovery

July 4, 2022

The landmark discovery of the Higgs boson at the LHC exactly ten years ago, and the progress made since then to determine its properties, have allowed physicists to make tremendous steps forward in our understanding of the universe. The Collider Physics Group at IFAE joined the ATLAS collaboration since its inception. For 30 years it has contributed to the design and construction of the experiment and the physics analysis program.

ATLAS observes elusive Higgs boson decay to a pair of bottom quarks

August 28, 2018

Six years after its discovery, the Higgs boson has at last been observed decaying to fundamental particles known as bottom quarks.

ATLAS observes direct interaction of Higgs boson with top quark

June 4, 2018

New results from the ATLAS experiment at the LHC reveal how strongly the Higgs boson interacts with the heaviest known elementary particle, the top quark.
