Production of $\phi$ -mesons in p+p, p+Pb and central Pb+Pb collisions at $E_{beam}$=158 A GeV
Yields and phase space distributions of $\phi-$ mesons emitted from $p$+$p$ (minimum bias trigger), $p$+Pb (at various centralities) and central Pb +Pb collisions are reported (E/sub beam/=158 A GeV). The decay $\phi$ to K/sup +/K/sup -/ was used for identification. The $\phi$ / $\pi$ ratio is found...

| description | Yields and phase space distributions of $\phi-$ mesons emitted from $p$+$p$ (minimum bias trigger), $p$+Pb (at various centralities) and central Pb +Pb collisions are reported (E/sub beam/=158 A GeV). The decay $\phi$ to K/sup +/K/sup -/ was used for identification. The $\phi$ / $\pi$ ratio is found to increase by a factor of 3.0+or-0.7 from inelastic p+p to central Pb+Pb. Significant enhancement in this ratio is also observed in subclasses of $p$+$p$ events (characterized by high charged-particle multiplicity) as well as in the forward hemisphere of central $p$+Pb collisions. In Pb+Pb no shift or significant broadening of the $\phi$ - peak is seen. (28 refs). |
