Light Stop: MSSM versus R-parity violation
W. Porod, D. Restrepo, J. W. F. Valle
Abstract
We discuss the phenomenology of the lightest stops in models where R-parity is broken by bilinear terms. In this class of models we consider scenarios where the R-parity breaking two-body decay stop1 -> tau + b competes with the leading three-body decays stop1 -> W+ + b + neutralino1, H+ + b + neutralino1, b slepton+i neutrinol, b sneutrinol l+ (l=e, mu, tau). We demonstrate that the R-parity violating decay can be the dominant one. In particular we focus on the implications for a future electron posistion Linear Collider.
