This diploma thesis examines b-tagging algorithms with the sPlot technique and the pTrel method based on Cern data from the Atlas experiment and data from simulation. Deviations between experimental data and the simulation data are investigated thoroughly based on statistical analysis using the sPlot technique and the pTrel method for evaluating the performance of b-tagging algorithms used at Cern.
In principle, the calibration and continuous calibration of b-tagging algorithms with the sPlot technique and the pTrel method is investigated in this thesis.
