Gaussian-distribution analysis of transverse momentum spectra of K_0^S and K^(*0) in 200 GeV collisions.

In this paper, we use the Gaussian distribution to analyze transverse momentum spectra of K_0^S and K^(*0) at midrapidity in d +Au, Cu+Cu and p+p Collisions at 200 GeV. The two-component Gaussian distribution can approximately agree with the experimental data and the three-component distribution can perfectly agree with the data in the given range. Moreover, there is a significantly positive correlation between the temperature and the collision centrality.
