A dibaryon-pole search in the complex energy plane has been performed for Jp = 2+ and 3- states in terms of the three channel (pp, NƊ, πd) K-matrix simulation of the pp-pp, pp-πd and πd-πd amplitudes of the phaseshift analysis. We have found the resonance poles in the mass region of NN(2170) for 2+ and of NN(2250) for 3-. One remarkable finding is small pp elasticities (≤ for 2+ and ≤ 0.04 for 3-)

1351The maximal-decoupling procedure of ~ collective submanifold fQrmulated within the framework of the time·dependent Hartree·Fock theory is applied to a classical Hamiltonian system numerically investigated by Henon and Heiles. The periodic orbits are obtained from the condition that the terms with zero denominators vanish in the collective Hamiltonian and they are in agreement with the numerical results by computer simulation. at University of Hawaii -Manoa on June 29, 2015 http://ptp.oxfordjournals.org/ Downloaded from 1352 K. Takabayashi*) The self-consistent collective-coordinate method (SeC), which has been developed in Refs. 2) and 3), extracts a collective submanifold by the so-called invariance principle of the (time-dependent) Schrodinger equation, while the present formulation does the same thing by imposing a maximal-decoupling condition on the classical canonical equations of motion to which the TDHF equation reduces_ at University

A dibaryon·pole search in the complex· energy plane has been performed for J P =2+ and 3-states by the three· channel (pp, NLl, 7fd) K-matrix simulation of the PP-PP, pp·7fd and 7fd'7fd amplitudes of the phase· shift analyses. We have found resonance poles in the mass region of NN(2170) for 2+ and of NN(2250) for 3-. The average mass and width of the solutions are 2162 MeV and 48 MeV for 2+ and 2166 MeV and 133 MeV for 3-. Small PP elasticities (:S0.02 for 2+ and 0.04:Sfor 3-) are suggested.
