Amplifying muon-to-positron conversion in nuclei with ultralight dark matter

Purushottam Sahu, Manibrata Sen

We present an analysis of the lepton-number and lepton-flavour-violating process of muon-to-positron conversion $\hat{I}{¼}^{-}+N\to e^{+}+N^{\prime }$, in the presence of an ultralight sc…
