The two won the award for their world on the theory of Higgs boson, the so-called "God particle".

The Nobel Academy has been unable to contact Peter Higgs to tell him about the prize, as he is walking in the Scottish Highlands.

Francois Englert (Univ. Libre de Bruxelles) & Peter W. Higgs (Univ. of Edinburgh) have been awarded 2013 #NobelPrize in #Physics.
