N ov 2 00 7 nd scattering lengths from a quark - model based NN interaction
نویسنده
چکیده
We calculate the doublet and quartet neutron-deuteron scattering lengths using a nonlocal nucleon-nucleon interaction fully derived from quark-quark interactions. We use as input the NN S0 and S1D1 partial waves. Our result for the quartet scattering length agrees well with the experimental value while the result for the doublet scattering length does not. However, if we take the result for the doublet scattering length together with the one for the triton binding energy they agree well with the so-called Phillips line. Typeset using REVTEX

In a scenario where the constituent quarks are composite systems, Generalized Parton Distributions (GPDs) are built from wave functions to be evaluated in a Constituent Quark Model (CQM), convoluted with the GPDs of the constituent quarks themselves. The approach permits to access the full kinematical range corresponding to the DGLAP and ERBL regions, so that cross sections for deeply virtual C...

A model in which the soft collisions of the nucleon are described in terms of interactions of its two constituents (a quark and a diquark) is proposed. When adjusted to describe precisely the elastic proton-proton scattering data and supplemented with the idea of wounded constituents, the model accounts rather well for the centrality dependence of particle production in the central rapidity reg...

Available data on large-angle nucleon-deuteron elastic scattering N d → dN below the pion threshold give a signal for three-body forces. There is a problem of separation of possible subtle aspects of these forces from off-shell effects in two-nucleon potentials. By considering the main mechanisms of the process N d → dN , we show qualitatively that in the quasi-binary reaction N + d → (N N) + N...

We calculate nα phase-shifts and scattering observables in the resonating-group method, using the nuclear-matter G-matrix of an SU6 quark-model NN interaction. The G-matrix is generated in the recent energy-independent procedure of the quark-model NN interaction with the continuous prescription for intermediate spectra, by assuming an appropriate Fermi momentum kF = 1.2 fm . The nα RGM interact...

We study the nucleon-nucleon interaction in the isoscalar-scalar channel using the chiral unitary approach. The t-matrix of the pion-pion scattering in this channel is summed up to all orders using the B-S equation. We find that the calculated results at long distances are close to those of the σ-exchange interaction. In addition, there appears a shorter range repulsion in this channel.
