Title:phi
Meson Production in p+p Collisions at 200 GeV Measured by the PHENIX
Experiment at the Relativistic Heavy Ion Collider
Abstract:
Study of relativistic nuclear collisions might hint on possibility to
create a nuclear matter, which isdifferent from ordinary. The PHENIX
experiment at the Relativistic Heavy Ion Collider investigates
nuclear matter through the programmatic study of collisions of
different particle species at different energies. By studying Au+Au,
d+Au and p+p collisions at 200 GeV one can understand, how nuclear
matter can change. phi meson serves as an effective probe to
characterize nuclear collisions. Measurements of production rates of
the phi meson in p+p collisions are essential, since p+p collisions
serve as a common reference to all other collisions.
First measurements of the production rates of the phi meson in p+p
collisions at 200 GeV are presented. Comparison of the phi meson
production in p+p collisions with that in Au+Au and d+Au collisions
indicates that Au+Au and d+Au collisions create a matter, which is
different from the ordinary nuclear matter and cannot be described by
conventional models.
