Carving out the end of the world or (superconformal bootstrap in six dimensions)

We bootstrap N = (1, 0) superconformal field theories in six dimensions, by analyzing the four-point function of flavor current multiplets. Assuming E-8 flavor group, we present universal bounds on the central charge C-T and the flavor central charge C-J. Based on the numerical data, we conjecture that the rank-one E-string theory saturates the universal lower bound on C-J, and numerically determine the spectrum of long multiplets in the rank-one E-string theory. We comment on the possibility of solving the higher-rank E-string theories by bootstrap and thereby probing M-theory on AdS(7)XS(4)/Z(2).
