ATLAS provides first measurement of the W-boson width at the LHC

The discovery of the Higgs boson in 2012 slotted in the final missing piece of the Standard Model puzzle. Yet, it left lingering questions. What lies beyond this framework? Where are the new phenomena that would solve the ...

Deeper insight into Higgs boson production using W bosons

Discovering the Higgs boson in 2012 was only the start. Physicists immediately began measuring its properties, an investigation that is still ongoing as they try to unravel if the Higgs mechanism is realized in nature as ...

ATLAS reports first observation of WWW production

The ATLAS Collaboration at CERN announces the first observation of "WWW production": The simultaneous creation of three massive W bosons in high-energy Large Hadron Collider (LHC) collisions.

Large Hadron Collider ATLAS moves into top gear for Run 3

After over three years of upgrade and maintenance work, the Large Hadron Collider began its third period of operation (Run 3) in July 2022. Since then, the world's most powerful particle accelerator has been colliding protons ...

Search for heavy bosons sets new limits

Since discovering the Higgs boson in 2012, the ATLAS Collaboration at CERN has been working to understand its properties. One question in particular stands out: why does the Higgs boson have the mass that it does? Experiments ...

Searching for heavy new particles with the ATLAS Experiment
