upper threshold applied on the relative isolation is 0.06 for electrons and muons in the [$\PW(\ell\PGn)\PH(\ccbar)$]{}channel and 0.15 and 0.25 for electrons and muons respectively in the [$\PZ(\ell\ell)\PH(\ccbar)$]{}channel. Charged PF candidates not originating from the PV, as well as PF candidates identified as electrons or muons, are not considered in the sum [@CMS:2019kuk]. The isolation of electrons and muons is also corrected for the estimated energy that is contributed to the isolation region by neutral particles originating from pileup. In the case of electrons, the latter is estimated by an effective jet area from the measured neutral energy density [@Khachatryan:2015hwa], while for muons, the $\Delta\beta$-correction method [@Sirunyan:2018] is applied.

Jets are reconstructed by clustering the PF candidates with the anti-algorithm [@Cacciari:2008gp; @Cacciari:2011ma] using a distance parameter $R$. The jet momentum is determined as the vectorial sum of all PF candidate momenta in the jet, and is found in simulation to be within 5 to 10% of the true momentum over the full detector acceptance and range of considered in this analysis. The raw jet energies are then corrected to establish a relatively uniform response of the calorimeter in $\eta$ and a calibrated absolute response in . Additional corrections to account
