Quantum Nucleardynamics as an SU(2)_N x U(1)_Z Gauge Theory
Abstract
It is illustrated that quantum nucleardynamics (QND) as an SU(2)_N x U(1)_Z gauge theory, which is generated from quantum chromodynamics (QCD) as an SU(3)_C gauge theory through dynamical spontaneous symmetry breaking, successfully describes nuclear phenomena at low energies. The proton and neutron assigned as a strong isospin doublet are identified as a colorspin plus weak isospin doublet. Massive gluon mediates strong interactions with the effective coupling constant G_R/\sqrt{2} = g_n^2/8 M_G^2 \simeq 10 GeV^{2} just like Fermi weak constant G_F/\sqrt{2} = g_w^2/8 M_W^2 \simeq 10^{5} GeV^{2} in the GlashowWeinbergSalam model where g_n and g_w are the coupling constants and M_G and M_W are the gauge boson masses. Several explicit evidences such as cross sections, lifetimes, nucleonnucleon scattering, magnetic dipole moment, nuclear potential, gamma decay, etc. are shown in support of QND. The baryon number conservation is the consequence of the U(1)_Z gauge theory and the proton number conservation is the consequence of the U(1)_f gauge theory.
