| 英文摘要 | We have searched for the signature of 3- and 4-body decays of pair-produced scalar top quarks (stop) in the inclusive final state containing an electron, a muon, and significant missing transverse energy using a sample of p (p) over bar events corresponding to 108.3 pb(-1) of data collected with the D empty set detector at Fermilab. The search is done in the framework of the minimal supersymmetric standard model assuming that the neutralino (chi(1)(0)) is the lightest supersymmetric particle and is stable. No evidence for a signal is found and we derive cross-section upper limits as a function of stop ((t) over tilde) and neutralino masses in different decay scenarios leading to the blvchi(1)(0) final state.
