Higgs Into Fermions
The ATLAS experiment released today preliminary results that show evidence, with a significance of 4.1 standard deviations that the Higgs boson decays to two taus, which are fermions. This is exciting news. But what makes this measurement important?
Full Coverage for ATLAS Muons
Hold out your hand and in one minute hundreds of muons will have passed through your palm. Muons are one of the high-energy cosmic ray particles that can pass through most solid structures – even the ATLAS detector's calorimeter, which is designed to absorb particles and measure their energy. A specific system is required to measure muons. Until now, the ATLAS muon system was almost completed, but not quite.
Englert and Higgs get the Nobel
On 8 October, the 2013 Nobel Prize in physics was awarded to Professors François Englert and Peter Higgs "for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, and which recently was confirmed through the discovery of the predicted fundamental particle, by the ATLAS and CMS experiments at CERN's Large Hadron Collider".
ATLAS and CMS physicists cheered the announcement at CERN and Marrakech, where ATLAS members were attending a collaboration meeting.
