           "On the necessity of massless modes in AdS_3 integrability"


             címmel tartandó szemináriumára.

Kivonat:
We recently showed that the Bethe equations for AdS_3 integrability 
describe the spectrum of a much smaller sector than was the case for 
AdS_5/CFT_4. The reason is that wrapping corrections enter much earlier 
than before, thanks to the presence of massless modes. This explains 
(most of) a mismatch that was seen in one of the classic tests of 
AdS/CFT integrability, namely the study of circular spinning strings 
from which Hernandez & Lopez deduced the one-loop dressing phase for 
AdS_5. My talk will start by reviewing this test, then translate to 
AdS_3 to see the mismatch, and finish by explaining what we now 
understand about the origin of this. (Reference:
