Search for an exotic decay of the Higgs boson to a pair of light pseudoscalars in the final state with two muons and two b quarks in pp collisions at 13 TeV

A search for exotic decays of the Higgs boson to a pair of light pseudoscalar particles is performed under the hypothesis that one of the pseudoscalars decays to a pair of opposite sign muons and the other decays to . Such signatures are predicted in a number of extensions of the standard model (SM...
