- Abstract
- Dark Matter is one of the biggest mysteries in physics of our time, with an overwhelming amount of evidence for its existence but lack of direct observation (at time of writing). The focus of this thesis is to reimplement an ATLAS analysis used for Dark Matter searches in the mono-H(bb) channel, and use that analysis in order to study the signal of a new particle called Dark Higgs. The Dark Higgs comes from assuming that Dark Matter particles acquire their mass in the same manner as Standard Model particles i.e via a Higgs mechanism in the dark sector. The signal samples used for this analysis are generated with a Monte Carlo simulation at truth level. The analysis was implemented in Rivet version 2.5.4 and the results produced show that... (More)
