Observations on the chiral algebra of two-dimensional supersymmetric quantum field theories |
|
Résumé |
I will review basic properties of the chiral algebra in a two-dimensional
supersymmetric quantum field theory with at least two chiral supercharges and
discuss two applications in RG flows from UV Lagrangian theories to non-trivial
compact superconformal field theories. The first application is a solution to an
old problem: finding UV representatives of so-called “non-toric” and “non-
polynomial” marginal deformations of a (2,2) SCFT obtained as a non-linear sigma
model with target space a Calabi-Yau hypersurface in a toric variety. The second
application points out a new problem in an old class of field theories: a mystery
in the IR dynamics of seemingly well-behaved Landau-Ginzburg theories with (0,2)
supersymmetry. |
