As already announced, the Nobel Prize in Physics for 2013 has been awarded to François Englert and Peter W. Higgs “for the theory of how particles acquire mass” (see Press Release). They published the theory independently of each other 1964 in Physical Review Letters (see PRL). In 2012, physicists at the CERN found the particle predicted by Higgs and his colleagues.
