Crunching multiverse to solve two physics puzzles at once

The discovery of the Higgs boson was a landmark in the history of physics. It explained something fundamental: how elementary particles that have mass get their masses. But it also marked something no less fundamental: the ...

CMS collaboration homes in on Higgs boson's lifetime

The Higgs boson doesn't stick around for long. Once it is created in particle collisions, the famed particle lives for a mere less than a trillionth of a billionth of a second or, more precisely, 1.6 x 10-22 seconds. According ...

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

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 ...

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 ...

Under the radar: Searching for stealthy supersymmetry

The standard model of particle physics encapsulates our current knowledge of elementary particles and their interactions. The standard model is not complete; for example, it does not describe observations such as gravity, ...

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 ...
