- W1982941566 abstract "We study the dimensional continuation of the sphere free energy in conformal field theories. In continuous dimension d we define the quantity $$ tilde{F} $$ =sin(πd/2) log Z, where Z is the path integral of the Euclidean CFT on the d-dimensional round sphere. $$ tilde{F} $$ smoothly interpolates between (−1) d/2 π/2 times the a-anomaly coefficient in even d, and (−1)(d+1)/2 times the sphere free energy F in odd d. We calculate $$ tilde{F} $$ in various examples of unitary CFT that can be continued to non-integer dimensions, including free theories, double-trace deformations at large N, and perturbative fixed points in the ϵ expansion. For all these examples $$ tilde{F} $$ is positive, and it decreases under RG flow. Using perturbation theory in the coupling, we calculate $$ tilde{F} $$ in the Wilson-Fisher fixed point of the O(N) vector model in d = 4 − ϵ to order ϵ 4. We use this result to estimate the value of F in the 3-dimensional Ising model, and find that it is only a few percent below F of the free conformally coupled scalar field. We use similar methods to estimate the F values for the U(N) Gross-Neveu model in d = 3 and the O(N) model in d = 5. Finally, we carry out the dimensional continuation of interacting theories with 4 supercharges, for which we suggest that $$ tilde{F} $$ may be calculated exactly using an appropriate version of localization on S d . Our approach provides an interpolation between the a-maximization in d = 4 and the F-maximization in d = 3." @default.
