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 ...
Microscopic model for the magnetic subsystem in HoNi2B2C
(American Physical Society, 1998)
We demonstrate that the system of localized magnetic moments in HoNi2B2C can be described by the four-positional clock model. This model, at a proper choice of the coupling constants, yields several metamagnetic phases in ...
Kaon dispersion relation and flow in relativistic heavy-ion collisions
(American Physical Society, 1996)
Within the framework of a relativistic transport model (ART) for heavy-ion collisions at AGS energies, we examine the effects of a kaon dispersion relation on the transverse flow of kaons and their transverse momentum and ...
Splitting of the giant monopole and quadrupole resonances in Sm-154
(American Physical Society, 1999)
Strength functions for the isoscalar giant monopole and quadrupole resonances in Sm-154 have been measured with inelastic scattering of 240 MeV alpha particles at small angles. The E0 strength distribution containing ...
Medium Effects on Kaon and Antikaon Spectra in Heavy-Ion Collisions
(American Physical Society, 1993)
In the linear chiral perturbation theory, both kaon and antikaon masses decrease in dense matter. There is also a repulsive vector potential for the kaon and an attractive one for the antikaon. With these effects included ...
