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 andCMS experiments at CERN’s Large Hadron […]

Higgs Into Fermions

The ATLAS experiment released preliminary results on 26 Nov 2013 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? read more...

Dealing with Data

In the first run of the Large Hadron Collider, almost a billion proton-proton collisions took place every second in the centre of the ATLAS detector. That amounts to enough data to fill 100,000 CDs each second. If you stacked the CDs on top of each other, in a year it would reach the moon four […]

ALPHA Is #1 Physics Breakthrough Of The Year

Physics World, the international physics magazine produced by the Institute of Physics, has named ALPHA's recent trapping of antihydrogen as part of the #1 physics breakthrough of 2010, jointly with the ASACUSA Collaboration's formation of antihydrogen in a 'cusp' trap. The complete list of ten breakthroughs from 2010 includes measurements of the atmosphere of an exoplanet 130 light-years […]

ALPHA Probes Antimatter Gravity

Physicists have long wondered if the gravitational interaction between antimatter and matter might be different than that between matter and itself. Do atoms made of antimatter, like antihydrogen, fall at a different rate to those made of matter, or might they even fall up -- antigravity? There are many arguments that make the case that […]
