Die neutrinoinduzierte diffraktive Produktion von $D_s$-Mesonen und der Zerfall $D_s \rightarrow \tau\nu_\tau$

Low $Q^2$ interactions with low momentum transfer play an important role in exploring the regime between deep inelastic scattering and diffractive processes. In particular, neutriNO1induced diffrac tive production is interesting as there is only a small number of particles in the final state and all quantum numbers are known, reflecting the structure of the weak current. In this thesis the po ssibilities are studied, to search for neutriNO1induced diffractive $D_s^*$ with the subsequent decay $D_s^*\rightarrow D_s \rightarrow \tau \rightarrow \mu$ in the CHORUS (WA95) experiment.
