A simple BRST system with quadratically constrained ghosts
Michael Chesterman
I present a toy model for the Berkovits pure spinor superparticle. It is a D=1, N=2 superparticle with no physical degrees of freedom. We study the cohomology in various ways, in p…
On the cohomology and inner products of the Berkovits superparticle and superstring
Michael Chesterman
We describe the complete cohomology of the Berkovits BRST operator for the superparticle. It is non-zero at eight ghost numbers, splitting into two quartets, the members of each qu…
Gaugino and meson condensates in N=1 SQCD from Seiberg-Witten curves
Michael Chesterman
We calculate gaugino and meson condensates in N=1 SQCD theory with SU(N_c) gauge group and N_f < 2N_c matter flavours, by deforming the pure N=2 Super-Yang-Mills plus fundamental m…
A quantum BRST anti-BRST approach to classical integrable systems
Michael Chesterman, Marcelo B. Silka
We reformulate the conditions of Liouville integrability in the language of Gozzi et al.'s quantum BRST anti-BRST description of classical mechanics. The Das-Okubo geometrical Lax…
Ghost constraints and the covariant quantization of the superparticle in ten dimensions
Michael Chesterman
We present a modification of the Berkovits superparticle. This is firstly in order to covariantly quantize the pure spinor ghosts, and secondly to covariantly calculate matrix elem…
Exploring the second class constraint quantization approach proposed by Batalin and Marnelius
Michael Chesterman
I extend upon the paper by Batalin and Marnelius, in which they show how to construct and quantize a gauge theory from a Hamiltonian system with second class constraints. Among the…
