Spin in relativistic quantum theory
W. N. Polyzou, W. Glöckle, H. Witała
We discuss the role of spin in Poincaré invariant formulations of quantum mechanics.
Deuteron disintegration in three dimensions
K. Topolnicki, J. Golak, R. Skibinski +4
We compare results from the traditional partial wave treatment of deuteron electro-disintegration with a new approach that uses three dimensional formalism. The new framework for t…
A Three-Dimensional Treatment of the Three-Nucleon Bound State
J. Golak, K. Topolnicki, R. Skibinski +3
Recently a formalism for a direct treatment of the Faddeev equation for the three-nucleon bound state in three dimensions has been proposed. It relies on an operator representation…
Different Methods for the Two-Nucleon T-Matrix in the Operator Form
J. Golak, R. Skibinski, H. Witala +4
We compare three methods to calculate the nucleon-nucleon t-matrix based on the three-dimensional formulation of J. Golak et al., Phys. Rev. C 81, 034006, (2010). In the first plac…
Dineutron and the three-nucleon continuum observables
H. Witala, W. Gloeckle
We investigate how strong a hypothetical 1S0 bound state of two neutrons would affect different observables in the neutron-deuteron reactions. To that aim we extend our momentum sp…

Aye Mya Phyu, Hiroyuki Kamada, Jacek Golak +3
Using the complex energy method, the problem of nucleon-deuteron scattering is solved with a simple three-body force having a separable form. Our results are compared with the resu…

Long-range contributions to the three-nucleon force that have been recently worked out in chiral effective field theory at next-to-next-to-next-to-leading order are for the first t…
Three-nucleon force in relativistic three-nucleon Faddeev calculations
H. Witala, J. Golak, R. Skibinski +3
We extend our formulation of relativistic three-nucleon Faddeev equations to include both pairwise interactions and a three-nucleon force. Exact Poincare invariance is realized by…

A recently developed procedure for a partial wave decomposition of a three-nucleon force is applied to the pi-pi, pi-rho and rho-rho components of the Tucson-Melbourne three-nucleo…
Momentum-space 3N Faddeev calculations of hadronic and electromagnetic reactions with proton-proton Coulomb and three-nucleon forces included

K. Khaldi, Ch. Elster, W. ~Glöckle
The continuum Faddeev equations for the neutron-neutron-alpha (n-n-) system are formulated for a general interaction as well as for finite rank forces. In addition, the capture…

I. Fachruddin, Ch. Elster, J. Golak +3
We extend a new treatment proposed for two-nucleon (2N) and three-nucleon (3N) bound states to 2N scattering. This technique takes momentum vectors as variables, thus, avoiding par…

The direct treatment of the Faddeev equation for the three-boson system in 3 dimensions is generalized to nucleons. The one Faddeev equation for identical bosons is replaced by a s…
