Explaining ATOMKI, $(g-2{)}_{\mu }$, and MiniBooNE anomalies with light mediators in $U(1{)}_H$ extended model

Sumit Ghosh, Pyungwon Ko

We consider $U(1{)}_H$ extensions of Type-I 2HDM plus a singlet scalar ${\varphi }_H$, introducing a new Higgs doublet $H_2$ and a singlet ${\varphi }_H$ charged under $U(1{)}_H$. The SM Higgs doublet $…
