Are there exactly solvable CFTs?

+ 6 like - 0 dislike
193 views

I am wondering if there are CFTs such that n-point correlation functions in them of the fields (may be the primaries or of some notion of twist fields) is exactly known.

  • Are there such?

  • Aren't minimal models supposed to have this property?

  • Even if not exactly known, can the n-point functions (may be when written as a conformal block expansion) be written order-by-order as a power series in the central charge? (..I guess there is some theorem about the asymptotic exponential dependence of the conformal blocks on the central charge (reference help? ) and I want to know if 1/c corrections to that are known..)

Are your $n$-point correlation functions in genus zero?

@S.Carnahan That would be the simplest scenario I would like to know of. (..if you can say something about higher genus then that is more exciting ;P..)

Did you look at the work of Dotsenko and Fateev from mid 1980s. They computed correlation functions of a number of 2d conformal field theories.

@JoséFigueroa-O'Farrill Can you kindly refer to any paper that you have in mind? Is it known by some name that I can may be trace in the Francesco et. al's book?

@user6818, I have lent my copy of the book by di Francesco et al., I'm afraid, but the papers I have in mind are the following: dx.doi.org/10.1016%2F0550-3213%2884%2990269-4 and dx.doi.org/10.1016%2FS0550-3213%2885%2980004-3 .
