A study of $Z\rightarrow b\bar{b}$ at Tevatron

The energy measurement of b-quark jets suffers from biases due to the peculiarities of hadronization and decay of origionating B-hadron. The impact of these effects can be estimated by reconstructing the mass of $Z\rightarrow b\bar{b}$. From the sample of 2$fb^{-1}$ of Data collected by D0 experiment $p \bar{p}$ collisions at Tevatron, we will show how Z signal can be identified and measured. The measurement of reconstructed mass of Z can be used to determine the jet energy scale factors for b-quark jets which allows a reduction of uncertainity in high $p_{T}$ physics analysis. This analysis can help to explore suitable triggering and other necessary tools for Low mass Higgs discovery at Tevatron.
