Description
A search for a new massive particle X decaying into a Higgs boson H and a second particle, Y using an anomaly detection algorithm is presented. The dataset collected by the CMS experiment in proton-proton collisions at 13 TeV center-of-mass energy is analyzed. The final states with Higgs bosons decaying to a bb quark pair and reconstructed a single large-radius jets are considered. This search focuses on the final states with the Y decay products reconstructed as a large-radius jets. The identification of the Y particle is enhanced by computing the anomaly score of its candidate jet using a variational autoencoder, allowing the simultaneous search for multiple Y decay modes with a single analysis.
