18:30 → 18:45 A search for $\mu \to e\gamma$ with the highest sensitivity to date in the MEG II experiment

The MEG II experiment has been searching for lepton-flavour-violating $\mu \to e\gamma$ with the highest sensitivity in the world, utilising the most intense DC muon beam at PSI and innovative high-resolution detectors.
We published the results last year using the first two years of data, in which there was no event excess and that the most stringent upper limit on the branching ratio of $\mu \to e\gamma$ was set to $1.5 \times 10^{-13}$ at 90% confidence level.
This talk will present the motivation, essence and challenges of a rare-decay search in the MEG II experiment.
