New Higgs decays to axion-like particles

We investigate the interactions of a light scalar with Higgs boson and second-generation fermions, which trigger new rare decays into $4\mu$, $2\mu 2\gamma$, $6\mu$ $4\mu 2j$. recast current LHC searches to constrain these develop collider analyses for those channels are only poorly tested by existing studies. With currently collected data we can probe branching ratios as small $1.5 \times10^{-5}$, $8.7 $5.7 \times10^{-8}$ $1.6 \times10^{-7}$, respectively. For High-Luminosity run, considered here involve 3 ab$^{-1}$ integrated luminosity, numbers go down $1.3 $2.0 \times10^{-6}$, $3.0 \times10^{-9}$ $5.4 \times10^{-9}$, also comment on other that remain still unexplored.
