Description

The charge asymmetry is a property of top-quark pair production predicted by the Standard Model which has already been measured at various center-of-mass energies. This analysis would like to follow up on the previous measurement, which observed non-zero charge asymmetry at 4.7 sigma significance level. This effort aims to overcome the previous successful measurement and claim the discovery of the charge asymmetry phenomenon. Larger data set comprised of full Run2 and partial Run3 data should help to diminish the statistical uncertainty hence contribute to larger significance of the result.
This talk will be focused on the reconstruction method and unfolding procedure used in the analysis. Preliminary results of some related studies will be presented.
