Abstract:
The program for simulation of the experiment for investigation of subthreshold $K^+$-production in COSY (Julich, Germany) was created. It gave the possibility to elaborate the method for selection of events connected with $K^+$-production which may be realized in the 1-st order trigger. It was shown that the reliable detection of $K^+$ from the secondary particles mass spectrum can be performed with the help of the goodness-of-fit criterion $\omega_n^3$.
