Massive Ghost Confinement, Dipole Equation and Multipole States in Quadratic Gravity
Ichiro Oda
We investigate the problem of confinement of massive ghost, which violates the unitarity of the physical S-matrix, in quadratic gravity on the basis of a manifestly covariant and l…
Confinement of Massive Ghost in Quadratic Gravity
Ichiro Oda
In the framework of the covariant canonical formalism of quadratic gravity, we consider the problem of confinement of massive ghost which violates the unitarity of the physical S-m…
Color Confinement and Massive Gluon in Superfield Formalism
Ichiro Oda
In connection with the question of confinement of massive ghost in quadratic gravity (QG), color confinement in quantum chromodynamics (QCD) has been reconsidered in the superfield…
Bound States in Scalar Theory with Fourth-order Derivative Term
Ichiro Oda
We consider a problem whether bound states are made in a scalar theory with a fourth-order derivative term or not. After rewriting the theory to a standard scalar theory with secon…
