A bstractThe results of a search for direct pair production of the scalar partner to the top quark using an integrated luminosity of 20.1 fb−1 of proton-proton collision data at s$$ \sqrt{s} $$ = 8 TeV recorded with the ATLAS detector at the LHC are reported. The top squark is assumed to decay via t¯→tχ¯10$$ \overline{t}\ \to t{\overline{\chi}}_1^0 $$ or t¯→bχ¯1±→bW*χ¯10$$ \overline{t}\ \to b{\overline{\chi}}_1^{\pm }\ \to b{W}^{\left(*\right)}{\overline{\chi}}_1^0 $$, where χ¯10χ¯1… CONTINUE READING
