Left: Projection of the combined unfolding matrix for jets with particle-level momentum $45 < p_\mathrm{T,\,ch\;jet}^\mathrm{part} < 50$ GeV/$c$. The matrix is obtained from the combination of the detector response and background fluctuation matrices, which are also shown as projections (see text for details) Right: Probability distribution of the relative difference betweenparticle-level (generated true) and detector-level charged jet transverse momentum for jets with different momenta. The effect of background fluctuations is included for the jets reconstructed at detector level. Characteristic values of the distributions are summarized in Table [1].
