Simple Evaluation of the Chiral Jacobian with the Overlap Dirac Operator

Hiroshi Suzuki

The chiral Jacobian, which is defined with Neuberger's overlap Dirac operator of the lattice fermion, is explicitly evaluated in the continuum limit without expanding it in the gau…

TeV gamma-ray observations of southern BL Lacs with the CANGAROO 3.8m Imaging Telescope

M. D. Roberts, S. A. Dazeley, P. G. Edwards +32

Observational and theoretical results indicate that low-redshift BL Lacertae objects are the most likely extragalactic sources to be detectable at TeV energies. In this paper we pr…

A Large-scale CO Imaging of the Galactic Center. II. Dynamical Properties of Molecular Clouds

T. Oka, T. Hasegawa, F. Sato +2

The data from the Nobeyama Radio Observatory 45 m telescope Galactic Center CO survey have been analyzed to generate a compilation of molecular clouds with intense CO emission in t…

A High Velocity Cloud near the Center of the Galaxy

T. Oka, G. J. White, T. Hasegawa +3

We report the detection of a peculiar molecular cloud, CO 0.02-0.02, lying about 5' Galactic-east from the center of the Galaxy. (12)CO images taken with NRO 45 m telescope showed…

Quantum Exchange Algebra and Exact Operator Solution of -Toda Field Theory

Y. Takimoto, H. Igarashi, H. Kurokawa +1

Locality is analyzed for Toda field theories by noting novel chiral description in the conventional nonchiral formalism. It is shown that the canonicity of the interacting to free…

Invariant Regularization of Supersymmetric Chiral Gauge Theory. II

Takuya Hayashi, Yoshihisa Ohshima, Kiyoshi Okuyama +1

By undertaking additional analyses postponed in a previous paper, we complete our construction of a manifestly supersymmetric gauge-covariant regularization of supersymmetric chira…
