Gauge anomaly with vector and axial-vector fields in six dimensional curved space
Satoshi Yajima, Kohei Eguchi, Makoto Fukuda +1
Imposing the conservation equation of the vector current for a fermion of spin at the quantum level, a gauge anomaly for the fermion coupling with non-Abelian vector…
Chiral anomaly for V-A fields in four- and six-dimensional curved space
S. Yajima, K. Eguchi, M. Fukuda +3
The chiral U(1) anomalies associated with a fermion of spin 1/2 interacting with nonabelian vector and axial-vector fields in four- and six-dimensional curved space are given in te…
Generalized BF state in quantum gravity
Shinji Yamashita, Satoshi Yajima, Makoto Fukuda
The BF state is known as a simple wave function that satisfies three constraints in canonical quantum gravity without a cosmological constant. It is constructed from a product of t…
Studies of resonance conditions on neutrino oscillations in matter
Y. Kamo, S. Yajima, Y. Higasida +2
We analytically discuss the resonance conditions among several neutrinos in matter. The discriminant for the characteristic equation of the Hamiltonian is expressed by the coeffici…
Analytical calculations of four-neutrino oscillations in matter
Yuki Kamo, Satoshi Yajima, Yoji Higasida +3
We analytically derive transition probabilities for four-neutrino oscillations in matter. The time evolution operator giving the neutrino oscillations is expressed by the finite su…
Asymptotic expansion coefficients of the heat kernel in Riemann-Cartan space
S. Yajima, Y. Higasida, K. Kawano +1
By applying the covariant Taylor expansion method, the fifth lower coefficients the asymptotic expansion of the heat kernel associated with a fermion of spin 1/2 in Riemann-Cartan…
