In this paper, we investigated the production of and meson yields in pp and collisions at in the rapidity range of . In addition to this, we also examined and meson production in collisions at in the rapidity range of . The and meson yields are studied as a function of . The ratio and the Nuclear Modification factor of particles yields are also analyzed in this paper. The PYTHIA8, EPOS-LHC and EPOS1.99 are the event generators used for simulations. The aim of using these event generators is to check for their validity for strange particles production at various LHC energies. We also used PYTHIA8 CR Mode2 to see its result in comparison with PYTHIA8 default model. Transverse momentum ranges for and mesons production in pp collisions are and , respectively. Similarly for and meson analysis in heavy-ion collisions at in range of is considered for both mesons and likewise in the collisions at distributions were plotted for and in the values of and . PYTHIA8 default model gave higher predictions for all kinds of interactions of system. But for meson in collisions, PYTHIA8 CR Mode2 described the ALICE data very well. However, EPOS-LHC and EPOS1.99 did not give good results as compared to the PYTHIA8 default model. It seems that all of the Monte Carlo simulation codes provided very good predictions for the particle ratios. In case of , the EPOS-LHC model gave good prediction for while for meson the PYTHIA8 CR Mode2 provided higher prediction very close to the ALICE data.
