"Evidences for D(G,s) Theories"*

Location: Bloomberg Lecture Hall

Time: 1:30 PM

Speaker(s): Michele Del Zotto, SISSA

*Description:* In the past three years some aspects of the duality in 
between representation theory of associative algebras and N=2 
supersymmetric theories in four dimensions have proven to be crucial for 
understanding the so-called BPS-quiver theories. Very recently, as a 
natural consequence of the 2d/4d correspondence combined with the 
aforementioned duality, evidences for the existence of infinitely many 
N=2 superconformal field theories have been found: For each simple 
simply-laced Lie group G, there exists an infinite tower of N=2 SCFT's 
having (at least) flavor group G. These theories are labeled D(G,s), 
where s is a positive integer. In the talk, after a review of the 
formalism, I will discuss such evidences, and explain some of the basic 
properties of these N=2 superconformal models.
