φ meson measurement via K^+K^- decay channel in d+Au collisions at√sNN= 200 GeV
Abstract
The measurement of the line shape of the φ meson invariant mass spectrum in relativistic heavy ion collisions is a powerful tool to search for in-medium modifications of vector meson properties (mass and/or width) as chiral symmetry restoration is approached. Consisting of a ss pair, the φ meson can also be used to probe strangeness production. The current results of φ meson production in the K^+K^- channel detected by the PHENIX central arm spectrometer in d+Au collisions will be presented. The system size and centrality dependece of the φ spectral shapes and yields will be studied through the comparison with results obtained in Au+Au and p+p collisions.
