Interactions at large distances and spin effects in nucleon-nucleon and nucleon-nuclei scattering
J. R. Cudell, E. Predazzi, O. V. Selyugin
The momentum-transfer dependence of the slopes of the spin-non-flip and spin-flip amplitudes is analysed. It is shown that the long tail of the hadronic potential in impact paramet…
Behavior of the Hadron Potential at Large Distances and Properties of the Hadron Spin-flip Amplitude
E. Predazzi, O. V. Selyugin
The impact of the form of the hadron potential at large distances on the behaviour of the hadron spin-flip amplitude at small angles is examined. The -dependence of the spin-fli…
RHIC and diffraction in pp Spin-flip
A. F. Martini, E. Predazzi
We argue that diffraction (Pomeron) contribution is present in the pp spin-flip amplitude. RHIC polarization will be able to prove (or disprove) this conjecture.
Pomeron contribution to Spin-flip
A. F. Martini, E. Predazzi
The pp polarization data confirm the presence of a diffractive-like (Pomeron) contribution in the spin-flip amplitude. The extrapolation to RHIC energies does not appear very promi…
Preon Trinity - a new model of leptons and quarks
Jean-Jacques Dugne, Sverker Fredriksson, Johan Hansson +1
A new model for the substructure of quarks, leptons and weak gauge bosons is discussed. It is based on three fundamental and absolutely stable spin-1/2 preons. Its preon flavour SU…
Of dips and structures
P. Desgrolard, M. Giffon, E. Martynov +1
A detailed analysis of the existence of high energy secondary diffractive dips and structures in the extrapolations of the fits to the data is given. The existence of these dips an…
