On resummation of the irregular conformal block | S. Alekseev
; M. Litvinov
; | Date: |
8 Dec 2018 | Abstract: | We discuss the resummation procedure of the superpotential in 4d
$mathcal{N}=2$ SYM theory without matter from the point of view of 2d
Liouville conformal field theory, utilizing the AGT correspondence. We identify
contributions of different descendants of the intermediate state, defining a
conformal block in CFT, to the superpotential and answer the question, which
descendants are responsible for the appearance of the branch cuts in the
superpotential. | Source: | arXiv, 1812.3387 | Services: | Forum | Review | PDF | Favorites |
