Y-Formalism and Curved Beta-Gamma Systems
Pietro Antonio Grassi, Ichiro Oda, Mario Tonin
We adopt the Y-formalism to study beta-gamma systems on hypersurfaces. We compute the operator product expansions of gauge-invariant currents and we discuss some applications of th…
Gravitational Higgs Mechanism with a Topological Term
Ichiro Oda
We investigate the Higgs mechanism for gravity, which has been recently put forward by 't Hooft, when the Polyakov-type action for scalar fields is added to the original action. We…
Y-formalism and ghost in the Non-minimal Pure Spinor Formalism of Superstrings
Ichiro Oda, Mario Tonin
We present the Y-formalism for the non-minimal pure spinor quantization of superstrings. In the framework of this formalism we compute, at the quantum level, the explicit form of t…
A Relation Between Topological Quantum Field Theory and the Kodama State
Ichiro Oda
We study a relation between topological quantum field theory and the Kodama (Chern-Simons) state. It is shown that the Kodama (Chern-Simons) state describes a topological state wit…
Trapping of Nonabelian Gauge Fields on a Brane
Ichiro Oda
We show that as in abelian gauge fields, nonabelian gauge fields are also trapped on a brane in the Randall-Sundrum model by applying a new mechanism based on topological Higgs mec…
A New Mechanism for Trapping of Photon
Ichiro Oda
We propose a new mechanism for trapping bulk gauge field, giving rise to a massless photon on a flat Minkowski 3-brane in the Randall-Sundrum model in five space-time dimensions. T…
