Description
Many modern jet clustering algorithms, such as the anti-$k_T$ algorithm, were proposed after LEP had concluded. This poses a unique opportunity and challenge for analyzing the archived $e^+e^-$ data from the LEP era. Jets are re-clustered with the $e^+e^-$ variant of the anti-$k_T$ algorithm across a wide range of resolution parameters, ranging from 0.1 to 1.2. As a clean test of jets and QCD without the complication of hadronic initial states, electron-positron collisions serve as a benchmark to compare with analogous measurements in heavy-ion collisions, and examining jet productions with different resolution parameters is a way to probe parton shower and hadronization mechanisms. We will discuss the methodologies to calibrate jets developed specifically for $e^+e^-$ collisions. In addition, unfolding processes are carried out for ALEPH $e^+e^-$ data samples with various resolution parameters. The unfolding procedure is solidified with unfolding PYTHIA 6.1 simulation samples. Comparison between unfolded ALEPH data and simulation from various generators, including PYTHIA 8, SHERPA, HERWIG, and PanScales, are presented. We will also discuss potential future work.
