Unwatch ••• Yesterday, 11:47 PM #1 PrashantGokaraju In socalled 'string field theory', the strings are described by a field theory in spacetime, rather than a CFT on the worldsheet. This field theory turns out to be chernsimons theory, which has action dαi1 ∧ αi1 + αi1 ∧ αi1 ∧ αi1. The propagator between two points is a correlator 〈O1chernsimonsO2chernsimons〉 as shown in the following picture. The density operator is of the form eW[J]eβH MY PF Correlators of operators in the worldsheet CFT are not propagators, but amplitudes to emit particles or states from the points where the two operators are located. Since the correlator of the chernsimons operators is the propagator, whatever notion which corresponds to these operators on the worldsheet can be located only on the circular edges of the following picture. https://www.physicsforums.com/threads/chernsimonstheory.989564/ 1/3 5/26/2020 chernsimons theory  Physics Forums In chernsimons theory, things like eiS[path] can be states rather than amplitudes. Normally states are functions on space, but this is a function of a path or history. What is the notion corresponding to chernsimons theory on the worldsheet?
