Probing lepton-flavour universality with $$K\rightarrow \pi \nu \bar{\nu }$$ K → π ν ν ¯ decays

Abstract We analyse the rare processes $$K\rightarrow \pi \nu \bar{\nu }$$ K → π ν ν ¯ in view of the recent hints of violations of lepton-flavour universality (LFU) observed in B meson decays. If, as suggested by present data, the new interactions responsible for LFU violations couple mainly to the...
