"N=2 orbifolds and their marginal deformations”


címmel tartandó szemináriumára.


Kivonat:



I will revisit type IIB string theory on AdS_5 x S^5/Z_k orbifold spaces 
which are dual to N=2 "necklace" quiver gauge theories with equal gauge 
coupling constants. Since these models are integrable, we can compute 
the entire spectrum of these theories at any value of the universal 
coupling constant. A recent modification of the hexagon formalism also 
allows for the determination of three-point functions and a comparison 
with localisation results. From the perspective of gauge theory it is 
natural to allow also for unequal couplings which introduces (k-1) 
marginal deformation parameters. In the bulk theory, these deformations 
are more mysterious and break the integrable structure of the orbifold 
theory. I will comment on our current understanding and open puzzles in 
the analysis of these models.
