The top band is disfavoured by the CAST search for solar axions [22] and by constraints from the evolution of horizontal-branch (HB) stars [23]. In the shaded area to the left, strong mixing in the intergalactic space (assuming the magnetic field of 1 nG) results in strong suppression ...
In section 3, after a quick review of the usual AdS3/CFT2 1While one may object that in this case the CFT we are deforming is either trivial or non-unitary, our point of view is that unitarity constraints do not play an essential role in the N →∞ limit in which we are working ...
