DESCRIPTION:A conformal field theory is characterised by the CFT data\, na
 mely the spectrum of scaling dimensions and OPE coefficients. The idea of 
 the conformal bootstrap is to use associativity of the operator algebra to
 gether with the symmetries of the theory to constraint the CFT data. For t
 he sector of operators with large spin one can actually use these ideas to
  obtain analytical results. It was recently understood how to set up a sys
 tematic expansion around this sector\, leading to analytic results to all 
 orders in inverse powers of the spin. We will show how to use this large s
 pin perturbation theory to obtain analytic results for vast families of CF
 Ts. Some of the applications include vector models\, weakly coupled gauge 
 theories and the computation of loops for scalar theories in AdS.
