“The Higgs Discovery: Understanding the Empty Space”
Dr Stathes Paganis
(Dept. of Physics and Astronomy, Univ. of Sheffield)
The 2013 Nobel prize in Physics was awarded to Englert and Higgs for
their work on the Higgs boson which was recently discovered by the
ATLAS and CMS experiments at CERN. Unlike the electromagnetic field,
the Higgs field is not zero in empty space. Non-zero quantum field means that the vacuum is filled with energy. Its presence not only provides mass to elementary particles but also explains the unification of the electromagnetic and the weak-nuclear forces. The colloquium will cover the Higgs story, its discovery and the new era of understanding of how this non-zero field was formed fractions of a second after the Big Bang.
