Measurement of muon polarization in $K^{+}\to {\pi }^0{\mu }^{+}{\nu }_{\mu }$ at a $\varphi$ factory

Paolo Privitera

The potentiality of an experiment measuring the muon polarization in $K^{+}\to {\pi }^0{\mu }^{+}{\nu }_{\mu }$ at a $\varphi$ factory is discussed, with particular attention to the possibility of reveal…
