## Abstract

We show that the bosonic decays of the lighter top and bottom squarks, i.e. t~\_1 -\> b~\_1 + (H^+ or W^+) and b~\_1 -\> t~\_1 + (H^- or W^-), can be dominant in a wide range of the MSSM parameters. Compared to the fermionic decays, such as t~\_1 -\> b + chargino\_j, these bosonic decays can have significantly different decay distributions. We also show that the effect of the supersymmetric QCD running of the quark and squark parameters on the t~\_1 and b~\_1 decay branching ratios is quite dramatic. These could have an important impact on the search for t~\_1 and b~\_1 and the determination of the MSSM parameters at future colliders.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
