Description
This is a first search for pair production of vector like tops, each decaying to a new scalar and a Standard Model (SM) top, with a consequent all-hadronic SM top decay. The signal region is optimized for a diphoton decay of one scalar, with the other treated inclusively. The final state exploits a clean experimental signature of two photons with two large-radius top-induced jets. This exotic decay channel tests the Large Hadron Collider (LHC) sensitivity to a two-dimensional mass excess, where the two masses correspond to the mass of the vector-like top partner and the new scalar. The search is performed on a sample of proton-proton collision events at a center of mass energy of 13 TeV and a corresponding total integrated luminosity of 138 fb−1, as recorded by the CMS experiment.
