Abstract
We review some recent results on computation of quantum corrections in conformal and massless higher spin theory.
Highlights
We shall review some recent results of the study of quantum corrections in theories containing infinite number of massless or conformal higher spin states [1,2,3,4,5,6,7].There is a long history of theoretical studies of higher spin theories

Massive HS fields appear in string theory and may become massless in a certain “tensionless" limit
Summary
We shall review some recent results of the study of quantum corrections in theories containing infinite number of massless or conformal higher spin states [1,2,3,4,5,6,7]. Theories dual to free adjoint U(N) CFT’s contain both massless tower of states plus infinite set of massive fields in AdS. On the CFT side we may consider the generating functional for correlators of currents Js(Φ) = Φ∗i Js Φi , Js ∼ ∂s introducing source fields hs These will have the interpretation of conformal higher spin (CHS) fields that are gauge fields for the infinite dimensional algebra of symmetries of the free scalar theory. We shall discuss some examples of quantum computations in massless and conformal HS theories that demonstrate this
