Small mass graviton propagator via finite-field-dependent BRST transformations in the critical dimension Siegel-Zwiebach action from string theory
Vipul Kumar Pandey, Ronaldo Thibes
We discuss the divergent graviton propagator massless limit problem in and show how it can be rigorously approached by interconnecting distinct gauge-fixed Siegel-Zwiebach g…
Note on an extended chiral bosons system contextualized in a modified gauge-unfixing formalism
Gabriella V. Ambrosio, Cleber N. Costa, Paulo R. F. Alves +2
We analyze the Hamiltonian structure of an extended chiral bosons theory in which the self-dual constraint is introduced via a control -parameter. The system has two second-clas…
Modified gauge unfixing formalism and gauge symmetries in the non-commutative chiral bosons theory
Cleber N. Costa, Gabriella V. Ambrósio, Paulo R. F. Alves +2
We use the gauge unfixing (GU) formalism framework in a two dimensional noncommutative chiral bosons (NCCB) model to disclose new hidden symmetries. That amounts to converting a se…
Gauge Symmetry of the Chiral Schwinger model from an improved Gauge Unfixing formalism
Gabriella V. Ambrosio, Cleber N. Costa, Paulo R. F. Alves +3
In this paper, the Hamiltonian structure of the bosonized chiral Schwinger model (BCSM) is analyzed. From the consistency condition of the constraints obtained from the Dirac metho…
