Higgs Boson

The Higgs boson is an elementary particle postulated by theorist  Peter Higgs. This particle is a remnant of the spontaneous Higgs_Bosonsymmetry breaking of electroweak interactions. It is this symmetry breaking that gives a mass to elementary particles. Our group has been pursuing the Higgs boson since the early nineties at experiments at LEP, Tevatron and now the Large Hadron Collider at CERN.

The Higgs has been discovered in 2012 culminating in a Nobel prize awarded to Peter Higgs and Francios Englert in 2013.

Our group is part of the ATLAS experiment and we are particularly interested in the fermionic couplings of the Higgs boson. We investigate these via two main search channels: Higgs decaying into a pair of tau leptons and Higgs decaying to b-quark anti-b-quark. We are currently analysing the data from Run 2 of the LHC, which started in 2015.
