Description
The measurement of the production cross section and transverse momentum ($p_T$) spectrum of $Z$ boson at the LHC provides first tests of the Standard Model (SM). This measurement could be sensitive to exotic physics processes in new energy regime. The $Z$ boson production is also a common background process for many other physics analyses and therefore it must be well understood. In this contribution, we will present a study of $Z$ boson production in association with jets with p-p collisions at a center-of-mass energy of 13.6 TeV at LHC, using leading-order event generators such as PYTHIA and HERWIG. The $Z$ boson has been reconstructed in $\mu^{+}\mu^{-}$ and $e^{+}e^{-}$ decay channels using different kinematic selections. These selection criteria involve each of the leptons having transverse momentum ($p_T > 20$ GeV) and within the central region ($|\eta|< 2.4$) of the detector. The jets (anti-$k_T$) produced are constrained within cone size of $r = 0.4$, having transverse momentum ($p_T$) of jets greater than 30 GeV and $|\eta|<1.3$. A comparison of $Z_{p_{T}}$ spectrum with both the generators will be presented.
