Non-chiral logarithmic couplings for the Virasoro algebra
This paper initiates the study of what we call non-chiral staggered Virasoro modules, indecomposable modules on which two copies of the Virasoro algebra act with the zero-modes L0 and acting non-semisimply. This is motivated by the puzzle recently reported in Vasseur et al (2012 Phys. Rev. Lett. 108 161602) involving a non-standard measured value, meaning that the value is not familiar from chiral studies, for the b-parameter (logarithmic coupling) of a c = 0 bulk conformal field theory.
