Estimation of the jet energy scale corrections using top quark events

A least-square kinematic fit using Lagrange multipliers is applied to enforce the W boson and top quark mass constraints in the reconstructed $pp\rightarrow t\overline{t}\rightarrow q\overline{q}b\mu\nu_{\mu}\overline{b}$ events. Residual corrections are estimated on the energy scale of the jets arising from both the light quarks in the W boson decay and the heavier bottom quark in the top quark decay. Utilizing the first integrated luminosity of 100 pb$^{-1}$ of proton collisions at 14 TeV detected by the CMS detector, an uncertainty smaller than 1\% can be obtained on the jet energy scale for both light and heavy jets
