DESCRIPTION:Speakers: Jose Calderon Infante (CERN)\n\nIn this talk\, I wil
 l discuss various aspects of the Distance Conjecture in AdS/CFT. First\, I
  will briefly introduce the Distance Conjecture and how to naturally tran
 slate it to the CFT side\, as encoded in the CFT Distance Conjecture. In 
 the second part\, I will sketch a proof of the first statement in this con
 jecture\, namely that higher-spin symmetry always lies at infinite distanc
 e in the conformal manifold of any local CFT in more than two dimensions.
  For the third part\, we will change gears from model-independent proofs t
 o asking more refined questions in well-known models. Specifically\, we w
 ill focus on a mini-landscape of supersymmetric CFTs in four dimensions w
 hich feature three distinct infinite distance limits distinguished by the 
 CFT Distance Conjecture parameter. Borrowing insights from the Swampland 
 program\, I will argue that these three limits correspond to three differ
 ent strings becoming tensionless in AdS. To support this claim\, I will di
 scuss how some properties of these CFTs\, such as their large N Hagedorn 
 temperature\, are determined solely by the CFT Distance Conjecture parame
 ter. I will also discuss how one of these limits nicely fits with the Type
  IIB string\, while another corresponds to a non-critical string theory i
 n AdS.\n \nPour être informé des prochains séminaires vous pouvez vous
