Search for light pseudoscalar boson pairs produced from Higgs boson decays using the 4$\ddot{I}„$ and 2$\hat{I}¼$2$\ddot{I}„$ final states in proton-proton collisions at $\sqrt{s}$ = 13 TeV

CMS Collaboration

A search for a pair of light pseudoscalar bosons (a${}_1$) produced in the decay of the 125 GeV Higgs boson is presented. The analysis examines decay modes where one a${}_1$ decays int…
