High Energy Theory Seminar

The enhanced super-Virasoro symmetries in 2d have allowed us to extract many BPS quantities exactly from 2d superconformal field theories (SCFT). In this talk, we will take advantage of our past knowledge about 2d (2,2) SCFTs, combining with the method of conformal bootstrap, to explore features of 2d (2,2) SCFTs beyond the protected quantities. This is made possible by an identification we derive between BPS N=2 superconformal blocks and ordinary Virasoro blocks (of a different central charge). We will discuss the bootstrap bounds on the non-BPS spectrum and their dependence on the conformal moduli or certain chiral ring coefficients of the SCFTs. We will also see how these bounds fit together with our existing knowledge about various solvable 2d models.
