S-matrix cluster properties dictate how the two-body dynamics is embedded in the three-nucleon mass operator (rest Hamiltonian). We find that for neutron laboratory energiesabove ≈20 MeV relativistic effects on Ay are negligible. For energies below ≈20 MeV dynamical effects lower the nucleon analyzing power maximum slightly by ≈2% and Wigner rotations lower it further up to ≈10%, thereby increasing disagreement between data and theory. This indicates that three-nucleon forces (3NF) must provide an even larger increase of the Ay maximum than expected up to now.}, pages = {034004-1--034004-13}, title = {Relativity and the low energy A(y) puzzle}, volume = {77}, year = {2008}, yomi = {カマダ, ヒロユキ} }
