Narrow Pentaquark States in a Quark Model with Antisymmetrized Molecular Dynamics
The exotic baryon Θ+(uudds̄) is studied with microscopic calculations in a quark model by using a method of antisymmetrized molecular dynamics(AMD). We predict narrow states, J = 1/2+(I = 0), J = 3/2+(I = 0), and J = 3/2(I = 1), which nearly degenerate in a low-energy region of the uudds̄ system. We discuss NK decay widths and estimate them to be Γ < 7 for the J = {1/2+, 3/2+}, and Γ < 1 MeV for ...

متن کاملMultifragmentation and Symmetry Energy Studied with Antisymmetrized Molecular Dynamics
The antisymmetrized molecular dynamics (AMD) simulations suggest that the isospin composition of fragments produced dynamically in multifragmentation reactions is basically governed by the symmetry energy of low-density uniform nuclear matter rather than the symmetry energy for the ground-state finite nuclei. After the statistical secondary decay of the excited fragments, the symmetry energy ef...
متن کاملProton inelastic scattering to continuum studied with antisymmetrized molecular dynamics.
Intermediate energy (p, p′x) reaction is studied with antisymmetrized molecular dynamics (AMD) in the cases of Ni target with Ep = 120 MeV and C target with Ep = 200 and 90 MeV. Angular distributions for various Ep′ energies are shown to be reproduced well without any adjustable parameter, which shows the reliability and usefulness of AMD in describing light-ion reactions. Detailed analyses of ...
متن کاملAntisymmetrized molecular dynamics of wave packets with stochastic incorporation of the Vlasov equation.
On the basis of the antisymmetrized molecular dynamics (AMD) of wave packets for the quantum system, a novel model (called AMD-V) is constructed by the stochastic incorporation of the diffusion and the deformation of wave packets which is calculated by Vlasov equation without any restriction on the one-body distribution. In other words, the stochastic branching process in molecular dynamics is ...
