A Dynamical Interpretation of Connes' Unimodularity Condition in Standard Model and Majorana Neutrino
Katsusada Morita, Yoshitaka Okumura
Standard model is minimally extended using the unitary group of Connes' color-flavor algebra. In place of Connes' unimodularity condition an extra…
Lorentz covariant field theory on noncommutative spacetime based on DFR algebra
Yoshitaka Okumura
Lorentz covariance is the fundamental principle of every relativistic field theory which insures consistent physical descriptions. Even if the space-time is noncommutative, field t…
Noncommutative gauge theory with arbitrary U(1) charges
Yoshitaka Okumura
It is well-known that the charge of fermion is 0 or in the U(1) gauge theory on noncommutative spacetime. Since the deviation from the standard model in particle physics has…
Lorentz invariant nonabelian gauge theory on noncommutative space-time and BRST symmetry
Yoshitaka Okumura, Katsusada Morita, Kouhei Imai
Lorentz covariance is the fundamental principle of every relativistic field theory which insures consistent physical descriptions. Even if the space-time is noncommutative, field t…
Left-right symmetric gauge model in a noncommutative geometry on
Yoshitaka Okumura
The left-right symmetric gauge model with the symmetry of is reconstructed in a new scheme of the noncommutative differential geome…
