41 %Charged leptons from the decay of ${W, Z}$ bosons, and the new physics
42 %we are searching for, are expected to be
43 %isolated from other activity in the event. For selected muon and
44 %electron candidates, a cone of $\Delta R <$~0.3 is constructed
45 %around the track direction at the origin and the scalar sum of the
46 %track transverse momenta and calorimeter energy deposits, projected onto
47 %a plane transverse to the beam, is calculated. ĘThe contribution from
48 %the candidate itself is excluded. Depending on analysis region, we require the value of this scalar sum
49 %to be less than 10-15\% of the candidate's transverse momentum to be considered as a prompt lepton.
