Indirect upper limits on ${\ell }_i\to {\ell }_j\gamma \gamma$ from ${\ell }_i\to {\ell }_j\gamma$

Fabiola Fortuna, Alejandro Ibarra, Xabier Marcano +2

We perform an effective field theory analysis to correlate the charged lepton flavor violating processes ${\ell }_i\to {\ell }_j\gamma \gamma$ and ${\ell }_i\to {\ell }_j\gamma$. Using the current upper bounds…
