``Good Propagation'' Constraints on Dual Invariant Actions in Electrodynamics and on Massless Fields
S. Deser, J. McCarthy, O. Sarioglu
We present some consequences of non-anomalous propagation requirements on various massless fields. Among the models of nonlinear electrodynamics we show that only Maxwell and Born-…
Large N and the Dine-Rajaraman problem
Jim McCarthy, Leonard Susskind, Andy Wilkins
We compute the effective action for scattering of three well-separated extremal brane solutions, in 11d supergravity, with zero p_ transfer and small transverse velocities. Using a…
Induced Chern-Simons terms
Jim McCarthy, Andy Wilkins
We examine the claim that the effective action of four-dimensional SU(2)_L gauge theory at high and low temperature contains a three-dimensional Chern-Simons term with coefficient…
Supersymmetry and gauge theory on Calabi-Yau 3-folds
J. M. Figueroa-O'Farrill, A. Imaanpur, J. McCarthy
We consider the dimensional reduction of supersymmetric Yang-Mills on a Calabi-Yau 3-fold. We show by construction how the resulting cohomological theory is related to the balanced…
Fusing the coordinates of quantum superspace
Peter Bouwknegt, Jim McCarthy, Peter van Nieuwenhuizen
We introduce the notion of a fused quantum superplane by allowing for terms in the defining relations. We develop the differential calculus for a large class of fused qu…
BV-Structure of the Cohomology of Nilpotent Subalgebras and the Geometry of (W-) Strings
Peter Bouwknegt, Jim Mccarthy, Krzysztof Pilch
Given a simple, simply laced, complex Lie algebra $\bfg$ corresponding to the Lie group , let $\bfnp$ be the subalgebra generated by the positive roots. In this paper we constru…
Chiral ring in the 4D W_3 string
Jim McCarthy
I summarize some recent results obtained in collaboration with P.~Bouwknegt and K.~Pilch on the spectrum of physical states in $\cW_3$ gravity coupled to matter. In particula…
Operator algebra of the 4D W_3 string
Peter Bouwknegt, Jim McCarthy, Krzysztof Pilch
The noncritical $\cW_3$ string is a model of $\cW_3$ gravity coupled to two free scalar fields. In this paper we discuss its BRST quantization in direct analogy with that of t…
The W_3 algebra: modules, semi-infinite cohomology and BV-algebras
Peter Bouwknegt, Jim McCarthy, Krzysztof Pilch
The noncritical string is a model of gravity coupled to two free scalar fields. In this paper we discuss its BRST quantization in direct analogy with that of the…
On the W-gravity spectrum and its G-structure
P. Bouwknegt, J. Mccarthy, K. Pilch
We present results for the BRST cohomology of $\cW[\bfg]$ minimal models coupled to $\cW[\bfg]$ gravity, as well as scalar fields coupled to $\cW[\bfg]$ gravity. In the latter case…
Ultra--Planck Scattering in D=3 Gravity Theories
S. Deser, J. McCarthy, Alan R. Steif
We obtain the high energy, small angle, 2-particle gravitational scattering amplitudes in topologically massive gravity (TMG) and its two non-dynamical constituents, Einstein and C…
Semi-infinite cohomology of W-algebras
P. Bouwknegt, J. McCarthy, K. Pilch
We generalize some of the standard homological techniques to $\cW$-algebras, and compute the semi-infinite cohomology of the $\cW_3$ algebra on a variety of modules. These computat…
Semi-infinite cohomology in conformal field theory and 2d gravity
Peter Bouwknegt, Jim McCarthy, Krzysztof Pilch
We discuss various techniques for computing the semi-infinite cohomology of highest weight modules which arise in the BRST quantization of two dimensional field theories. In partic…
BRST Analysis of Physical States for 2D (Super) Gravity Coupled to (Super) Conformal Matter
P. Bouwknegt, J. McCarthy, K. Pilch
We summarize some recent results on the BRST analysis of physical states of 2D gravity coupled to c<=1 conformal matter and the supersymmetric generalization.
Some aspects of free field resolutions in 2D CFT with application to the quantum Drinfeld-Sokolov reduction
P. Bouwknegt, J. McCarthy, K. Pilch
We review some aspects of the free field approach to two-dimensional conformal field theories. Specifically, we discuss the construction of free field resolutions for the integrabl…
Fock space resolutions of the Virasoro highest weight modules with c<=1
Peter Bouwknegt, Jim McCarthy, Krzysztof Pilch
We extend Felder's construction of Fock space resolutions for the Virasoro minimal models to all irreducible modules with . In particular, we provide resolutions for the r…
