| 英文摘要 | In this talk we briefly summarise our recent study (hep-ph/0007165) on searching for top squark at hadron colliders. The light top-squark (stop) if produced in hadron colliders in the form of the (t) over tilde (1) (t) over tilde (1) pair and decaying through the likely decay chain (t) over tilde (1) --> (χ) over tilde (+)b followed by (χ) over tilde (+) --> (χ) over tilde (0) f (f) over bar, can mimic closely a top quark event when the mass of the stop is close to that of the top quark. Because of the much lower production rate, the stop event can be buried under the top quark event sample. In order to uncover the stop event, specific selection cuts need to be applied. Through Monte Carlo simulation with suitable kinematic cuts, we found that such stop event can be extracted from the top quark sample and detected by the top counting experiments in the upcoming upgraded Tevatron and LHC. However, because of the small statistics of the Run I of the Tevatron, the stop signal remains hidden at Run 1. |
