Particle Physics is the study of the fundamental building blocks of the Universe and how they interact. The Standard Model (SM), our current best understanding of the Universe, is an extremely successful theory that predicts these interactions to a very high precision. Despite this success there are several fundamental questions that remain unanswered. The most pressing of these is how particles acquire mass. The most popular theory is known as the Higgs mechanism. This predicts that particles acquire mass by interacting with the Higgs field (similar to how charged particles interact with a magnetic field) and that a new particle the Higgs boson exists. 

The two decade long search for such a particle was recently successfully concluded with the discovery of a Higgs boson like particle at the Large Hadron Collider (LHC) at CERN. However, the discovery of this particle is only the beginning of a new era as it opens a window onto a previously unexplored region. Using data collected at the LHC, I study the properties of this new particle, which allows us to begin answering the fundamental question of how particles acquire mass and maybe also other long standing puzzles as well. In particular I'm searching for the dominant decay of the Higgs particle into a pair of b-quarks, which is a vital channel to fully explore the properties of this new particle.
