On the book Conformal Field Theory by Francesco, Mathieu and Senechal (the yellow book), in the derivation of the propagator kernel [itex]K(\delta t,\xi,\xi')[/itex] on (2.73), the signs on the first and second line just doesn't match.
On first line it has [itex]-\xi^+ T \xi'-{\xi'}^+ T \xi' [/itex] while the second line, after simplifying, has [itex]\xi^+ T \xi'-{\xi'}^+ T \xi' [/itex], which is necessary to identify the term with the derivatives.
However, tracing back up to the definition of the properties of the coherent states, I cannot find any way to fix this sign. Does anyone has encounter this part and have a solution?
(For those without the book, the page is attached)
