Search for an exotic decay of the Higgs boson to a pair of light pseudoscalars in the final state of two muons and two τ leptons in proton-proton collisions at sqrt{s}= 13 TeV
read the original abstract
A search for exotic Higgs boson decays to light pseudoscalars in the final state of two muons and two $\tau$ leptons is performed using proton-proton collision data recorded by the CMS experiment at the LHC at a center-of-mass energy of 13 TeV in 2016, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. Masses of the pseudoscalar boson between 15.0 and 62.5 GeV are probed, and no significant excess of data is observed above the prediction of the standard model. Upper limits are set on the branching fraction of the Higgs boson to two light pseudoscalar bosons in different types of two-Higgs-doublet models extended with a complex scalar singlet.

Search for Higgs boson decays into two neutral scalars with unequal masses in final states with b quarks and tau leptons in proton-proton collisions at $\sqrt{s}$ = 13 TeV
No statistically significant excess is observed in the search for Higgs decays to two neutral scalars with unequal masses, setting 95% CL upper limits between 0.9 and 36.8 pb depending on mass and decay scenario.

Probing axion in the DFSZ model
With right-handed neutrinos, DFSZ PQ charges depend only on PQ_φ; for m_A≈130 GeV, m_H±≈155 GeV and v_u∼few GeV the trilinear modifier κ_λ lies inside current experimental limits.
