The lightcone bootstrap and the spectrum of the 3d Ising CFT
The lightcone bootstrap and the spectrum of the 3d Ising CFT
We compute numerically the dimensions and OPE coefficients of several operators in the 3d Ising CFT, and then try to reverse-engineer the solution to crossing symmetry analytically. Our key tool is a set of new techniques for computing infinite sums of SL(2,R) conformal blocks. Using these techniques, we solve the …
