Structure of the field equations in N = 1 chiral supergravity
M. Tsuda, T. Shirafuji
We study the structure of linearized field equations in chiral supergravity (SUGRA) with a complex tetrad, as a preliminary to introducing additional auxiliary fields in or…

Dynamical torsion and torsion potential
Hong-jun Xie, Takeshi Shirafuji
We introduce a generalized tetrad which plays the role of a potential for torsion and makes torsion dynamic. Starting from the Einstein-Cartan action with torsion, we get two field…

Consistency of matter field equations in Ashtekar formulation
M. Tsuda, T. Shirafuji
The chiral Lagrangian including more than two spin-3/2 fields becomes complex in general when the self-dual connection satisfies its equation of motion, and the imaginary part of t…
