The CMS and ATLAS experiments at the Large Hadron Collider (LHC) has characterized the Standard Model and searched for evidence of new physics, both with unprecedented breadth, but with no sign of physics beyond the Standard Model. This is both an experimental triumph and a conundrum. With all of the particles predicted by the SM discovered, there is no single, obvious next target for searches, but most of the questions that motivated the construction of the LHC remain. I will talk about my research addressing one of the outstanding questions, baryogenesis, through searches for additional Higgs bosons. Looking to the future, I argue that we are entering an experiment-driven era, and will need the best possible multipurpose detectors for the high-luminosity LHC and future colliders. Particle tracking using pixellated silicon detectors is an essential component of this, and I will present recent developments in this technology for the high-luminosity LHC and beyond.
