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…
