“…Starting at Q 2 ≥ 1 GeV 2 the approximation of helicity conservation is accurate on the level of 2-3% [23] (for recent analysis see Ref. [24]). It is even smaller factor for the observables of reaction (1) in which no polarization degrees of freedom are fixed.…”

We develop a theoretical framework for calculation of high Q 2 exclusive electro-disintegration of A = 3 systems. The main result of this work is the calculation of the final state interaction of the struck energetic nucleon with recoil nucleons within the generalized eikonal approximation (GEA) which allows us to account for the finite and relatively large momenta of the bound nucleons in the nucleus. The important advantage of this approach is the possibility to study in a self-consistent way the short range correlations in nuclei. This is due to the fact that GEA does not require a stationary condition for recoil nucleons as conventional Glauber approximation does. As a result GEA treats explicitly the Fermi motion of recoil nucleons in the nucleus.

“…In our previous analysis of nucleon-nucleon (NN) elastic scattering data [1], the upper energy limit was extended from 2.5 to 3.0 GeV in the laboratory kinetic energy, T p , in order to accomodate higher-energy proton-proton (pp) scattering measurements from SATURNE II at Saclay and the EDDA Collaboration at COSY. Comparisons were made with the direct amplitude reconstruction (DAR) and partial-wave analysis (PWA) study of Ref.…”

“…In that case, an S-wave resonance with maximum spin was predicted. Experimental evidence of such resonance was found in the NN scattering data, in the 3 D 3 partial wave, therefore as a D-wave resonance in the NN scattering [7]. This prediction has been recently used as a possible explanation of the measured cross section of the doublepionic fusion of nuclear systems through the so-called Abashian-Booth-Crowe (ABC) effect [8] of theP ANDA Collaboration is precisely to study the interaction between D mesons and nucleons, therefore our prediction may be taken as a challenge to be tested at future experiments.…”

Abstract. We perform a study of the ND interaction within a chiral constituent quark model. This model has been completely tight in the description of the NN interaction and the baryon and meson spectra, therefore provides a parameter-free framework from where to address the problem of the charm −1 two hadron systems. We predict the existence of a unique bound state, D * with (T , S) = (1, 5/2), that would appear in the scattering ofD mesons on nucleons as a D wave state. This resonance resembles our findings in the system, that offered a plausible explanation to the cross section of double-pionic fusion reactions through the so-called ABC effect.The study of the chiral symmetry restoration in a hot and/or dense medium, the suppression of the J / production in heavy ion collisions, or the possible existence of exotic nuclei with heavy flavors are a few examples of problems where the correct understanding of the interaction between nucleons and D mesons is necessary. Indeed, the FAIR facility at GSI will soon allow to study the ND interactions inside nuclear matter [1]. However, before one can extract information from the incoming experiments, a good description of the same problem in free space has to be achieved. At this point one has to admit that there is a complete lack of experimental information at low energies. Therefore the conclusions extracted from generalizations of models that have been successful in the light-flavor sector may be helpful.We approach the study of the ND system (ND, ND * , D , D * ) from a chiral constituent quark model (CCQM) [2,3], which successfully described the NN interaction and the meson spectra in all flavors, with the hope that our predictions may be supported by the next generation of experiments to be done atP ANDA.In the CCQM, the wave function of a baryon-meson B i M j system can be written as: a
