Available in PDF, EPUB and Kindle. Book excerpt: First Measurement of[phi] meson production in Au+Au collisions has been conducted by E917 at BNL-AGS via selecting events with identified K[sup+]K[sup[minus]] pairs. Preliminary results on the invariant mass spectra of K[sup+]K[sup[minus]] pairs and the m[sub T] spectra are presented. Also, the inverse slope T, dN/dy, the ratio of[phi]/K[sup[minus]], ratio of[phi]/K[sup+]K[sup[minus]] and their centrality dependences are extracted in a rapidity range of y= 0.9-1.4. Indications on the possible mechanisms of[phi] production are discussed.

Book excerpt: The production of [phi] mesons from, central Si + Au collisions has been measured by E859 at the BNL-AGS by selecting events with identified KK− pairs. The values for the mass and width of the [phi] obtained from the invariant mass of the kaon pairs are consistent with those of the Particle Data Book. Preliminary results for the invariant 1/2[pi]m{sub T} d2n/dm{sub T}dy distribution and dN/dy are presented.

Book excerpt: The first measurements of[phi] meson production in Au-Au collisions at AGS energies are presented via the decay to K[sup+] K[sup[minus]]. A measurement of the centrality dependence of the yield shows an increase similar to that seen for the K[sup[minus]] with a spectral shape consistent with a relativistic Breit-Wigner distribution within the statistical errors of the present data set. Future analysis using the full data set with 4 times the statistics will allow a more accurate determination of the yields, slopes and spectral shapes.

Available in PDF, EPUB and Kindle. Book excerpt: We measured the production of [Phi] mesons in the collisions of 2.83 GeV protons with C, Cu, Ag, and Au at forward angles via the [Phi] → K+K- decay using the COSY-ANKE magnetic spectrometer. The [Phi] meson production cross section follows a target mass dependence of A0.56±0.02 in the momentum region of 0.6-1.6 GeV/c. Moreover, the comparison of the data with model calculations suggests that the in-medium [Phi] width is about an order of magnitude larger than its free value.

This book was released on 2012 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strong enhancement of production of strange particles, and in particular of [phi] mesons, in heavy ion collisions of sufficiently high energies has been predicted to be an indication of a formation of a new state of matter, composed of deconfined quarks and gluons and having a property of chiral symmetry, called Quark Gluon Plasma (QGP). Studying production of [phi] mesons is of special interest due to their small cross-section of interaction with non-strange hadrons and due to their long lifetime, which should allow [phi] mesons to decouple from the strongly interacting medium produced in heavy ion collisions early in time and to escape the medium before decaying, thereby preserving information about the conditions in which the mesons were produced. In addition, the decay properties of [phi] mesons have been predicted to be modified in a hadronic gas medium. The [phi] -> K+K~ decay is of particular interest since the mass of a [phi] meson in vacuum is very close to the mass of two charged kaons, and consequently, even a small change in the mass or the width of [phi] mesons or in the mass of kaons would have a strong effect on the decay properties. Measurement of [phi] meson production using the PHOBOS detector at the Relativistic Heavy Ion Collider (RHIC) has proven to be especially challenging due to a small acceptance of the PHOBOS spectrometer and due to a much lower than predicted yield of [phi] mesons in heavy ion collisions at the highest RHIC energy. The measurement required a development of a new tracking algorithm, specifically tailored to reconstruct charged kaons with a high efficiency in a high hit density environment, keeping at the same time the necessary computing time within feasible limits.
