[Mean number of pile-up jets vs mean number of interactions] The mean number of pile-up jets within |\eta| < 2.1 that pass various cuts on the reconstructed LCW-scale jet pT, versus the mean number of pile-up interactions per bunch crossing (< \mu >). A correction, dependent on the number of reconstructed primary vertices and <mu>, was applied to the jets in order to subtract the average pT offset induced by pile-up. A power law was used to extrapolate the pile-up jet multiplicity to <mu> = 150. Since these extrapolations are based on only two data points each, there is a very large uncertainty in the extrapolated pile-up jet multiplicity. eps file gif file | ![]() |

[Jet resolution vs pt]
The jet energy resolution (sigmapT/pT) measured for anti-kt jets with R = 0.4 within |eta|<0.8, versus the true jet pT, in the EM+JES calibration. The data points are fit with the function sigmapT/pT = sqrt{N2/pT^2 + S^2/pT + C^2, where N, S and C are the noise, stochastic and constant terms in the resolution. The resolution is measured for samples with different values of | ![]() |
