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 ...

ATLAS experiment measures top quark polarization

Unique among its peers is the top quark—a fascinating particle that the scientific community has been studying in detail since the 90s. Its large mass makes it the only quark to decay before forming bound states (a process ...

Searching for heavy new particles with the ATLAS Experiment

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 the supersymmetric bottom quark (and its friends)

When it comes to quarks, those of the third generation (the top and bottom) are certainly the most fascinating and intriguing. Metaphorically, we would classify their social life as quite secluded, as they do not mix much ...

Studying top quarks at high and not-so-high energies

CERN's Large Hadron Collider (LHC) is famous for colliding protons at world-record energies—but sometimes it pays to dial down the energy and see what happens under less extreme conditions. The LHC started operation in ...

ATLAS searches for pairs of Higgs bosons in a rare particle decay

Since the Higgs boson was discovered in 2012, scientists at the Large Hadron Collider (LHC) have been studying the properties of this very special particle and its relation to the fundamental mechanism essential to the generation ...

ATLAS finds evidence of a rare Higgs boson decay

Since the discovery of the Higgs boson in 2012, scientists in the ATLAS and CMS collaborations at the Large Hadron Collider (LHC) have been hard at work characterizing its properties and hunting down the diverse ways in which ...
