Abstract:

We calculated cross sections of a scalar charm production in the framework of an R-parity breaking SUSY model at HERA experiments. A scalar charm is produced by collision and decays into , which followed by , , and . Cross sections of an exact calculation using the GRACE system are compared with those from approximation methods with and without spin correlation.
