A search for the direct pair production of top squarks with a Higgs
|
| 4 |
|
|
boson in the final state has been performed using events with one or
|
| 5 |
|
|
two leptons, several jets and 3 or at least 4 b-tagged jets.
|
| 6 |
|
|
Signal regions are defined with requirements on the transverse mass
|
| 7 |
|
|
\mt\ or the invariant $\bbbar$ pair mass consistent with the Higgs
|
| 8 |
|
|
mass. The observed yields in the signal regions agree with the predicted backgrounds within the assessed uncertainties.
|
| 9 |
|
|
The results are interpreted in the context of a simplified model
|
| 10 |
|
|
with pair production of a heavier stop $\tilde{t}_{2}$ decaying to a
|
| 11 |
|
|
lighter stop $\tilde{t}_{1}$ via $\tilde{t}_{2}\rightarrow H
|
| 12 |
|
|
\tilde{t}_{1}$ and the results probe top squarks with masses up to about XXX GeV.
