A Note on the Superstring BRST Operator
J. N. Acosta, N. Berkovits, O. Chandia
We write the BRST operator of the N=1 superstring as where and are super-reparameterization ghosts. This provides a trivial proof that i…
Superspace Action for the First Massive States of the Superstring
N. Berkovits, M. M. Leite
Using the manifestly spacetime-supersymmetric version of open superstring field theory, we construct the free action for the first massive states of the open superstring compactifi…
Manifestly Covariant Actions for D=4 Self-Dual Yang-Mills and D=10 Super-Yang-Mills
N. Berkovits, C. Hull
Using an infinite number of fields, we construct actions for D=4 self-dual Yang-Mills with manifest Lorentz invariance and for D=10 super-Yang-Mills with manifest super-Poincaré in…
First Massive State of the Superstring in Superspace
N. Berkovits, M. M. Leite
Using the manifestly spacetime supersymmetric description of the four-dimensional open superstring, we construct the vertex operator in superspace for the first massive state. This…
Off-shell Supersymmetry versus Hermiticity in the Superstring
Nathan Berkovits
We point out that off-shell four-dimensional supersymmetry implies strange hermiticity properties for the N=1 RNS superstring. However, these hermiticity properties become natural…
The big picture
N. Berkovits, M. T. Hatsuda, W. Siegel
We discuss the conformal field theory and string field theory of the NSR superstring using a BRST operator with a nonminimal term, which allows all bosonic ghost modes to be paired…
