# Search for 3- and 4-body decays of the scalar top quark in $pp$ collisions at $s = 1.8$ TeV

## Abstract

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 pp- events corresponding to 108.3 pb−1 of data collected with the DØ detector at Fermilab. The search is done in the framework of the minimal supersymmetric standard model assuming that the neutralino (χ~01) 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 (~t̃) and neutralino masses in different decay scenarios leading to the  bℓνχ~01   final state.
