POSSIBLE EXCESS IN CHARGED CURRENT EVENTS WITH HIGH-Q(2) AT HERA FROMSTOP AND SBOTTOM PRODUCTION

We investigate a production process e(+)p --> (t) over tilde X --> (b) over tilde W+X at HERA, where we consider a decay mode (b) over tilde --> <(nu)over bar>(e)d of the sbottom in the framework of an R-parity breaking supersymmetric standard model. Both processes of the stop pr oduction e(+)d --> (t) over tilde and the sbottom decay (b) over tilde --> <(nu)over bar>(e)d are originated from an R-parity breaking super potential lambda(131)'(L) over cap(1) (Q) over cap(3) (D) over cap(1)( c). One of the signatures of the process should be a large missing tra nsverse momentum plus multijet events corresponding to hadronic decays of the W. It is shown that the signal could appear as an event excess in the charged current (CC) processes e(+)p --> nu X with the high Q( 2) at HERA. We compare the expected event distributions with the CC da ta recently reported by the H1 and ZEUS groups at HERA. Methods for ex tracting the signal from the standard CC processes are also discussed.
