# f(Q$_{0}$): ${{\boldsymbol t}}{{\overline{\boldsymbol t}}}$ Fraction of Events with a Veto on Additional Central Jet Activity in ${{\boldsymbol p}}{{\boldsymbol p}}$ Collisions at $\sqrt {s }$ = 7 TeV INSPIRE search

Q$_{0}$ denotes the threshold of the additional jet $p_T$.

1  CHATRCHYAN 2015 based on 5.0 fb${}^{-1}$ of data. The ${{\mathit t}}{{\overline{\mathit t}}}$ events are selected in the dilepton and lepton + jets decay channels. For other values of Q$_{0}$ see Table 5.
2  Based on 2.05 fb${}^{-1}$ of data. The ${{\mathit t}}{{\overline{\mathit t}}}$ events are selected in the dilepton decay channel with two identified ${{\mathit b}}$-jets.
