Back-to-back correlations of boson–antiboson pairs for anisotropic expanding sources
Back-to-back correlations of boson–antiboson pairs for anisotropic expanding sources
In the hot and dense hadronic sources formed in high energy heavy ion collisions, the particle interactions in medium might lead to a measurable back-to-back correlation (BBC) of boson-antiboson pairs. We calculate the BBC functions of $\phi\,\phi$ and $K^+K^-$ for anisotropic expanding sources. The dependences of the BBC on the …
