Search for a pseudoscalar boson in the mass range from 4 to 15 GeV produced in decays of the 125 GeV Higgs boson in the final states with two muons and two nearby tracks at $\sqrt{s}=13~\mathrm{TeV}$
A search is presented for pairs of light pseudoscalar bosons, in the mass range between 4 and 15$~\mathrm{GeV}$, produced in decay of the 125 GeV Higgs boson. The decay mode where one light boson decays into $\tau$ leptons, while the other one decays into a pair of $\tau$ leptons or muons, is consid...
