CMS Beyond SM particles decaying 2(to) Higgs, top and Gauge bosons (B2G) Public Physics Results

About the physics of the Beyond SM particles decaying 2(to) Higgs, top and Gauge bosons (B2G) group

The B2G group covers models of new physics featuring the decay of new resonances to heavy standard model objects such as top, W, Z, or Higgs bosons. In particular, we study exotic diboson resonances, partners of the top quark with vector-like properties (VLQ) as well as heavy resonances, such as W' and Z' resonances decaying to final states with top quarks. The typical final states signatures involve top quarks, Higgs bosons, vector bosons and/or b quarks, with significant Lorentz boosts. Such boosted topologies are exploited with dedicated reconstruction algorithms that were developed and became well established in the context of the analyses of Run 1 and Run 2 data.

The group maintains synergy with the overlapping analyses in the HIG, TOP, SUS, and EXO physics groups.

The B2G results from before July 2011 can be found in PhysicsResultsEXO and PhysicsResultsTOP .
