Three nucleon system(triton) was considered. Relativistic properties of this system were investigated. For this relativistic generalization of Faddeev approach was used. As two particle T-matrix which contained in relativistic Faddeev equation we used solution of Bethe-Salpeter equation. So eventually we had Bethe-Salpeter-Faddeev(BSF) equation for describe three nucleon system. As potential...

Experimental data on $pi N $ scattering in the elastic energy region $W leq 1.45 GeV $ are analyzed within the $K$-matrix approach with effective Lagrangians. The charge splitting in $delta^{++}_{33}$ and $delta^{0}_{33}$ phases obtained in the phase shift analysis is studied . It is shown that the change in the sign in the energy dependence of the phase difference can be obtained with...

In this talk we are going to discuss all-loop conjecture for integrands of reggeon amplitudes in N=4 SYM. In particular we will present a new gluing operation in momentum twistor space used to obtain reggeon tree-level amplitudes and loop integrands from corresponding expressions for on-shell amplitudes. The introduced gluing procedure is used to derive BCFW recursions both for tree-level...
