The CMS Collaboration remembers François Englert
The worldwide CMS Collaboration is deeply saddened by the passing of Belgian theoretical physicist François Englert at the age of 93. Together with his colleague Robert Brout, and independently of British physicist Peter Higgs, Englert’s pioneering work led to an understanding of the mechanism that explains how elementary particles acquire mass.
