| 英文摘要 | The light top-squark 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)--><()over tilde>(+)b followed by <()over tilde>(+)--><()over tilde>(0)f (f) over bar' can mimic closely a top quark event when the mass of the top squark is close to that of the top quark. Because of the much lower production rate, the top squark event can be buried under the top quark event sample. In order to uncover the top squark event, specific selection cuts need to be applied. Through Monte Carlo simulation with suitable kinematic cuts, we find that such a top squark event can be extracted from the top quark sample and detected by the top quark counting experiments in the upcoming upgraded Fermilab Tevatron and CERN LHC. However, because of the small statistics of run 1 of the Tevatron, the top squark signal remains hidden at run 1. |
