Description
The discovery of the Higgs boson by the ATLAS and CMS experiments in 2012 provided
important insight into the mechanism of electroweak symmetry breaking. In the Standard Model
(SM), a pair of Higgs bosons can be produced via top quark loops, or the Higgs boson self-
coupling. Apart from SM production modes, several beyond the Standard Model (BSM)
hypotheses predict heavy narrow width resonances that could decay to a pair of Higgs bosons. A
search for non-resonant and resonant Higgs boson pair production in the bbττ channel is presented
for 36.1 fb -1 of √s =13 TeV data taken by the ATLAS experiment at the Large Hadron Collider
(LHC).
Measuring the strength of the Higgs boson trilinear self-coupling will be the ultimate test of the
electroweak symmetry breaking mechanism and one of the primary goals of the High
Luminosity Large Hadron Collider (HL-LHC) project. A study on the HL-LHC prospects of the
SM di-Higgs production in the bbττ channel is presented in addition.
