Description
If nature is supersymmetric and not fine-tuned, higgsinos may well be within the reach of the ILC. In the NMSSM extended with right-handed neutrinos the right-handed sneutrino is a viable thermal dark matter candidate. We discuss how a light higgsino-type chargino could decay to a sneutrino and a charged lepton with a branching ratio O(10^-5). Such a decay will be unobservable at the LHC, but in an electron-positron collider the decay can be observed. The measurement of the branching ratio would allow us to estimate the size of the neutrino Yukawa couplings.
