Deuteron two-body photodisintegration is analysed within the framework of the Quark-Gluon Strings Model. The model describes fairly well the recent experimental data from TJNAF in the few GeV region. Angular distributions at different γ-energies are presented and the effect of a forward-backward asymmetry is discussed. New results from the QGSM for(More)
Deuteron two-body photodisintegration is analysed within the framework of the Quark-Gluon Strings Model. It is found that the forward-backward angle asymmetry predicted by the model is confirmed by the recent data at different photon energies from Jlab. New calculations for polarization observables, the cross section asymmetry Σ and the polarization(More)
The real and imaginary parts of the ¯ K 0 d scattering length are extracted from the ¯ K 0 d mass spectrum obtained from the reaction pp→d ¯ K 0 K + measured recently at the Cooler Synchrotron COSY at Jülich. We extract a new limit on the K − d scattering length, namely Im a≤1.3 fm and |Re a|≤1.3 fm. The limit for the imaginary part of the K − d scattering(More)
show that the energy shift of the 1s level of kaonic hydrogen is repulsive, Re a(K−p) < 0. Nevertheless, it is possible that the actual K−p interaction is attractive if the isoscalar Λ(1405) resonance is a bound state of the K̄N system [4, 5]. A fundamental reason for such a scenario is provided by the leading order term in the chiral expansion for the K−N(More)
Comparative Regge analysis of Λ, Σ 0 , Λ(1520) and Θ + production in γp, πp and pp reactions Abstract. Using the Quark-Gluon Strings Model – combined with Regge phenomenology – we perform a comparative analysis of Λ, Σ 0 , Λ(1520) and Θ + production in binary reactions induced by photon, pion and proton beams on the nucleon. We find that the existing(More)
