String-Inspired Gravity Coupled to Yang-Mills Fields
G. Amelino-Camelia, D. Bak, D. Seminara
String-inspired 1+1-dimensional gravity is coupled to Yang-Mills fields in the Cangemi-Jackiw gauge-theoretical formulation, based on the extended Poincaré group. A family of coupl…
String-Inspired Gravity with Interacting Point Particles
Dongsu Bak, Domenico Seminara
We reformulate two dimensional string-inspired gravity with point particles as a gauge theory of the extended Poincaré group. A non-minimal gauge coupling is necessary for the equi…
Area-Preserving Structure of Massless Matter-Gravity Fields in 1+1 Dimensions
G. Amelino-Camelia, D. Bak, D. Seminara
We derive anomalous Ward identities in two different approaches to the quantization of massless matter-gravity fields in 1+1 dimensions.
Area-preserving Structure and Anomalies in 1+1-dimensional Quantum Gravity
G. Amelino-Camelia, D. Bak, D. Seminara
We investigate the gauge-independent Hamiltonian formulation and the anomalous Ward identities of a matter-induced 1+1-dimensional gravity theory invariant under Weyl transformatio…
Perturbative Analysis of Nonabelian Aharonov-Bohm Scattering
Dongsu Bak, Oren Bergman
We perform a perturbative analysis of the nonabelian Aharonov-Bohm problem to one loop in a field theoretic framework, and show the necessity of contact interactions for renormaliz…
Non-Abelian Chern-Simons Particles and their Quantization
Dongsu Bak, R. Jackiw, So-Young Pi
A many--body Schrödinger equation for non--Abelian Chern--Simons particles is obtained from both point--particle and field--theoretic pictures. We present a particle Lagrangian and…
