130   \item Passes loose PFJet ID
131   \item \pt $ > 30$ GeV for determining the jet multiplicity, \pt $ > 15$ GeV for calculation of \Ht
132   \item For the creation of photon templates, the jet matched to the photon passing the photon selection described above is vetoed
133 < \item For the dilepton sample, jets are vetoed if they are within $\Delta R < 0.4$ from any lepton \pt $ > 20$~GeV passing analysis selection

135 > \item To reject PU jets, we require the jets to satisfy $\beta>0.2$, defined for each jet using the $d_Z$ of the tracks in the jet with

137 > To calculate $\beta$ we take the sum of the $p_{T}^{2}$ of the tracks associated to PFCandidates in the jet
