Heavy new physics
Given all the unsolved mysteries of particle physics, we expect that there are new particles to discover just around the corner. We may not have found them yet because they are more massive than anything we have ever observed.
When a heavy, new particle decays into lighter particles, they receive a kick of energy called a boost. This boost means that when the lighter particle decays, the produced particles are collimated.
Our group looks for boosted bosons decaying to jets. These could be coming from heavy new particles.
We have used boosted jets to search for extra dimensions, heavy gravitons, and new forces. We have probed whether standard model particles, assumed to be fundamental, could actually be composed of other particles.
We have looked for boosted W bosons, Z bosons, and Higgs bosons, decaying to b-quarks, light quarks, and tau leptons.
