A study of Zweig's rule using phi mesons in a broad band neutral beam
A study of Zweig's rule using phi mesons in a high energy photon beam has been performed. Measurement of the ratio sigma (gamma A -> phi pi pi A) / sigma (gamma A -> omega pi pi A) = 0.10 ± 0.02 is taken as evidence that there is not as strong suppression as could be expected. Other ratios show …

Flow of [phi] mesons in pPb collisions at the LHC with the CMS detector
… between unidentified charged particles and [phi]-mesons are shown over a wide pseudorapidity range ([delta] [eta] < 2) in pPb collisions. The data, collected during 2013 pPb run at a nucleon-nucleon center-ofmass energy of 5.02 TeV with the CMS detector, corresponds to a total integrated …

Incoherent Photoproduction of $\phi$ Mesons in Ultra-Peripheral Pb+Pb Collisions at $\sqrt{s_{NN}}$ = 5.02 TeV
… vector meson the most common final state. The $\phi$ meson is a vector meson composed of a strange and a anti-strange quark, with $\phi\rightarrow K^+ K^-$ as the dominant decay mode. The photoproduction of $\phi$ mesons has been studied in photon+proton collisions at HERA. However, no …

Production of omega and phi mesons by 193 GeV/c pions and 250 GeV/c protons on a beryllium target
Qmegas and phis were observed in di-muon events. Differential cross sections with respect to perpendicular momentum and Feynman-X for both meson types and both beam types are compared. When a simple parton fusion model is used to describe the Feymnan-X distributions the omega appears to be produced …

Measurement of [phi] meson production in Cu+Cu collisions at 200 GeV using the PHOBOS detector at RHIC
… 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 …

Heavy Quark Jet Rest Frame Identification Technique and Incoherent Phi Analysis AT ALICE
… as well as the photo-nuclear production of the Phi meson in Ultra Peripheral Collisions (UPCs) at ALICE. A unique jet identification technique was developed which substantially reduces the number of non-heavy flavor jets in a jet sample. Coherently produced Phi mesons are not observed at ALICE …

Search for the Decay B0 -> eta phi at the BABAR Experiment
… for the rare hadronic B meson decay B0 -> eta phi. It is based on 86 x 10^6 BB pairs recorded by the BABAR experiment at the Stanford Linear Accelerator Center between 1999 and 2002. phi mesons are reconstructed in the channel phi -> K+ K-. eta mesons are reconstructed in the channels eta …
