First Successful Test for Electroweak Theory

Led by researchers from IRFU, the ATLAS collaboration at CERN's LHC has performed experimental tests of a prediction of the electroweak theory in the Standard Model of particle physics. Starting from a collision between quarks, it has provided evidence, for the first time, of the simultaneous production of three bosons (boson W and two gamma photons) which signals the existence of a “WWγγ coupling”, closely related to the Higgs mechanism.

Super Resolution for Huge Radio Telescope Networks

A technique of signal processing based on the principle of “parsimony” can double the resolution of a network of radio telescopes. This achievement was proven by an international team led by researchers from IRFU through the comparison of real images from European radio telescope LOFAR (Low-Frequency Array) that had been treated with or without this technique.
