### Description

In the present work, we study the effect of mass-modifications of kaons ($K$) and antikaons ($\bar{K}$) on the experimental observables relevant for nucleus-nucleus collisions. The in-medium masses of $K$ and $\bar{K}$ mesons evaluated using effective hadronic chiral SU(3) mean field model are implemented in A Multi-Phase Transport (AMPT) model to calculate different experimental observables. The impact of finite density of the medium on the masses of $K$ and $\bar{K}$ mesons in chiral effective models is calculated through their interactions with nucleons whose properties are modified because of the presence of scalar and vector fields. Along with the usual Weinberg-Tomozawa term, we consider the impact of explicit symmetry breaking term and three range terms to calculate the in-medium masses using chiral model and the observables within AMPT model. Explicit consideration of different terms in the model will have substantial effect on the flow splitting between $K$ and $\bar{K}$ mesons. Along with the flow splitting, we also study the transverse mass spectra, production ratio and rapidity spectra of kaons and antikaons.
