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…
Dynamical Symmetry Breaking in Flat Space with Non-trivial Topology
Ken-ichi Ishikawa, Tomohiro Inagaki, Kenji Fukazawa +1
We consider a four-fermion theory as a simple model of dynamical symmetry breaking in flat space with non-trivial topology, motivated from recent studies in similar considerations…
Scalar and Spinor Two-Point Functions in Einstein Universe
T. Inagaki, K. Ishikawa, T. Muta
Two-point functions for scalar and spinor fields are investigated in Einstein universe ($R \otimes S^{\sN-1}$). Equations for massive scalar and spinor two-point functions are solv…
Dynamical Symmetry Breaking in Einstein Universe
K. Ishikawa, T. Inagaki, T. Muta
We investigate four-fermion interactions with -component fermion in Einstein universe for arbitrary space-time dimensions (). It is found that the effective potentia…
