Dual projection in a two-dimensional curved expanding universe
It is a well known result that the scalar field is composed of two chiral
particles (Floreanini-Jackiw particles) of opposite chiralities. Also, that a
Siegel particle spectrum is formed by a nonmover field (a Hull's noton) and a
FJ particle. In this work we show that in a scalar field spectrum, in a curved
expanding universe scenario, we can find two dynamical chiral fields.Comment: 6 pages, Revtex. Final version to appear in Int. J. Mod. Phys.
Superspace Formulation for the BRST Quantization of the Chiral Schwinger Model
It has recently been shown that the Field Antifield quantization of anomalous
irreducible gauge theories with closed algebra can be represented in a BRST
superspace where the quantum action at one loop order, including the Wess
Zumino term, and the anomalies show up as components of the same superfield. We
show here how the Chiral Schwinger model can be represented in this
formulation.Comment: 11 pages, Late
Chiral boson on a circle revisited
It is a well known result that the scalar field spectrum is composed of two
chiral particles (Floreanini-Jackiw particles) of opposite chiralities. Also,
that a Siegel particle spectrum is formed by a nonmover field (a Hull's noton)
and a FJ particle. We show here that, in fact, the spectrum of the chiral boson
on a circle has a particle not present in its currently well known spectrum.Comment: 11 pages, Latex. Final version to appear in Braz. J. Phy
