主　　题：top squark mono-top signature HE-LHC 

摘      要：Searching for the top squark(stop)is a key task to test the naturalness of *** from stop pair production,single stop production relies on its electroweak properties and can provide some unique *** the single production process pp→t^(~)1X(~)1→tX^(~)1^(0)X^(~)1^(-),the top quark has two decay channels:leptonic channel and hadronic *** this paper,we probe the observability of these two channels in a simplified minimal supersymmetric standard model *** find that,at the 27 TeV LHC with the integrated luminosity of L=15 ab^(-1),mt^(-)11900 GeV andμ750 GeV can be excluded at 2σthrough the leptonic mono-top channel,while m_(t^(-)1)1200 GeV andμ350 GeV can be excluded at 2σthrough the hadronic channel.
