In this paper, we make connection between CFT$_3$ three point correlation function of conserved currents and 4D amplitude general spin massless gauge field explicit. We do so by taking flat space limit momentum CFT show how they reproduce amplitudes. then out a mismatch number independent structures in 3D correlator covariant vertex higher fields. This is contrast with expectation that counting...

The authors address the question of if structure universe originates from quantum fluctuation, as assumed in inflation, or classical, thermal fluctuations could lead to same outcome. They study their previously proposed test (the analytical particular cosmological correlation functions) flat space where several aspects and details are much better defined. show that criterion is completely gener...

Let G be a simple complex Lie group, g be its Lie algebra, K be a maximal compact form of G and k be a Lie algebra of K. We denote by X → X the anti-involution of g which singles out the compact form k. Consider the space of flat g-valued connections on a Riemann sphere with three holes which satisfy the additional condition A(z) = −A(z). We call the quotient of this space over the action of th...
