| Abstract: This note presents an analysis searching for new physics through the process where a new massive particle, X, decays into a Higgs boson and a second particle, Y. The Higgs boson subsequently decays into a pair of b-quarks and the decay products of Y are assumed to produce a non-QCD-like, e.g. anomalous, jet. In the benchmark process, Y decays into $ \text W^+ \text W^- $ forming one large-area jet. A second benchmark process is also considered, where Y is a hadronically decaying top quark, originating from a vector-like quark decaying into a top quark and a Higgs boson. CMS data recorded at a centre-of-mass energy of 13 TeV in 2016-2018 and corresponding to 138 fb$ ^{-1} $ are analysed. In this analysis, the identification of the Y particle is enhanced by computing the anomaly score of its candidate jet using an autoencoder, allowing the simultaneous search for multiple Y decay modes with a single analysis. No significant excesses are observed and upper limits on the signal cross section for various masses of X and Y, at 95% confidence level, are placed. | ||
