The {phi} mean free path in hot hadronic matter

PDF Version Also Available for Download.

Description

We calculate the {phi} meson collision rate and mean free path in a hot hadronic gas. The Hidden Local Symmetry model is used to take into account interactions of {phi} mesons with pseudoscalar ({pi}, K) and vector mesons ({rho}, {omega}, K*, {phi}). In contrast to previous calculations we find a significantly small mean free path (around 1 fm at T=200MeV). This implies that {phi} mesons produced after hadronization in relativistic heavy ion collisions will not leave the collision region without scattering. The consequences of these findings to the analysis of {phi} yields are discussed.
