(LOS ANGELES TIMES) STOCKHOLM — Physicists Francois Englert of Belgium and Peter Higgs of Britain won the 2013 Nobel Prize in physics on Tuesday for their theoretical discoveries on how subatomic particles acquire mass.

Their theories were confirmed last year by the discovery of the so-called Higgs particle, also known as the Higgs boson, at a laboratory in Geneva, the Royal Swedish Academy of Sciences said.

The announcement, which was widely expected, was delayed by one hour, which is highly unusual. The academy gave no immediate reason, other than saying on Twitter that it was “still in session” at the original announcement time.
