Null Physical States in String Models
arXiv:1212.4429 · doi:10.1007/JHEP02(2013)030
Abstract
This note is a brief addendum to my article Nucl. Phys. B 864 (2012) 285, [arXiv: 1110.5510], which discusses the noghost theorem in Ramond sectors of string models. In this addendum we derive additional information about the structure of null physical states in the Ramond-Neveu-Schwarz model.
