Rho Meson in Dense Hadronic Matter
(American Physical Society, 1992)
The spectral function of a rho meson that is at rest in dense hadronic matter and couples strongly to the pion is studied in the vector dominance model by including the effect of the delta-hole polarization on the pion. ...
Suppression of Dilepton Production in Hot Hadronic Matter
(American Physical Society, 1995)
Dilepton production from pion-pion annihilation in a hot hadronic matter is studied using an effective chiral Lagrangian that includes explicitly vector mesons. We find that the production rate for dileptons with invariant ...
Observation of Narrow Structures in the P-P Elastic Analyzing Power
(American Physical Society, 1990)
(D,he-2) Reactions at E(d)=125.2 Mev
(American Physical Society, 1995)
We have measured cross sections for (d, He-2) induced reactions on the p-shell nuclei Li-6, C-12, and C-13 and the sd-shell nucleus Mg-24 at an energy of E(d)=125.2 MeV. The measured excitation energy spectra are very ...
Formation and Decay of Toroidal and Bubble Nuclei and the Nuclear-Equation of State
(American Physical Society, 1993)
Multifragmentation, following the formation of toroidal and bubble nuclei, is observed with an improved Boltzmann-Uehling-Uhlenbeck model for central Mo-92 + Mo-92 collisions. With a stiff equation of state, simultaneous ...
np-elastic analyzing power A(N0) at 485 and 788 MeV
(American Physical Society, 1996)
Measurements are reported for the np-elastic analyzing power from 30 degrees to 128 degrees c.m., at 485 and 788 MeV, with a typical precision of 0.005 and absolute accuracy of 2%. Results strengthen the isospin-0 phase-shift ...
K+ production in baryon-baryon and heavy-ion collisions
(American Physical Society, 1998)
Kaon production cross sections in nucleon-nucleon, nucleon-Delta, and Delta-Delta interactions are studied in a boson exchange model. For the latter two interactions, the exchanged pion can be on-mass shell
Pion flow and antiflow in relativistic heavy-ion collisions
(American Physical Society, 1996)
Within the framework of a relativistic transport model (ART 1.0) for heavy-ion collisions at AGS energies we study the transverse flow of pions with respect to that of nucleons using two complementary approaches. It is ...
K+ Total Cross-Sections on C-12 and Medium Effects in Nuclei
(American Physical Society, 1992)
The total cross sections for K+ mesons on carbon and deuterium nuclei have been measured at eleven momenta in the range 450-740 MeV/c. The experimental technique was of the standard transmission type. The K+ meson is the ...
Dilepton production from resonance scattering in hot hadronic matter
(American Physical Society, 1996)
Dilepton production from resonance scattering in hot hadronic matter is studied. Including the widths of these resonances, which enhance the phase space for dilepton production, we find that the production rate is significantly ...
