Book excerpt: This thesis presents various studies of K[sub s][sup 0] mesons carried out at the BABAR experiment. Studying multiplicities of K[sub s][sup 0] in B[bar B] decays provides deeper knowledge of the detector performance and produces an important physical result. The branching fraction of B[bar B][yields] K[sub s][sup 0]X decay is measured using 286 pb[sup -1] of data collected during the first year of physics running. The result obtained is BR(B[bar B][yields] XK[sub s][sup 0][yields][pi][sup+][pi][sup -])= 0.216[+-] 0.003(stat.)[+-] 0.015(syst.). Implications of this result to the presence of the new physics at TeV scale are discussed. The momentum spectrum of K[sub s][sup 0] coming from B[bar B][yields] XK[sub s][sup 0][yields][pi][sup+][pi][sup -] is also presented.
