Wave-Packet Effects: A Solution for Isospin Anomalies in Vector-Meson Decay
Kenzo Ishikawa, Osamu Jinnouchi, Kenji Nishiwaki +1
There is a long-standing anomaly in the ratio of the decay width for to that for at the level of . A similar anomaly exis…
Decay Pattern of Pygmy States Observed in Neutron-Rich 26 Ne
J. Gibelin, D. Beaumel, T. Motobayashi +23
Coulomb excitation of the exotic neutron-rich nucleus Ne26 on a Pb208 target was measured at 58 MeV/u in order to search for low-lying E1 strength above the neutron emission thresh…
Potential scatterings in space: (1) non-orthogonality of stationary states
Kenzo Ishikawa
Orthogonality of eigenstates of different energies and its implications in potential scattering are unlabeled. Scalar products of scattering states of different energies are found…
Topological interaction of neutrino with photon in the magnetic field -- Electroweak Hall effect
Kenzo Ishikawa, Yutaka Tobita
The effective interaction of a neutrino with a photon in magnetized plasma is obtained from a strong field expansion in the electroweak standard model. The interaction is expressed…
New effect in wave-packet scattering of quantum fields
Kenzo Ishikawa, Kenji Nishiwaki, Kin-ya Oda
We report calculations of a wave-packet amplitude of the two-body scattering , which leads to the measured probability in realistic experiments. We elucidate the dec…
Scalar scattering amplitude in Gaussian wave-packet formalism
Kenzo Ishikawa, Kenji Nishiwaki, Kin-ya Oda
We compute an -channel scalar scattering in the Gaussian wave-packet formalism at the tree-level. We find that wave-packet effects, including shifts of the…
