研究了包含非相同算子的相关器系统的共形自举。这种混合相关器的交叉对称约束和统一约束可以用半定规划的语言表述。我们将这种形式应用于具有2全局对称的三维cft中最简单的混合相关器系统。对于领先的2-奇数算子σ和2-偶数算子λ,我们得到了允许维度的数值约束(Δσ, Δϵ),假设σ和λ是理论中唯一相关的标量。这些约束在(Δσ, Δϵ)空间中产生一个小的封闭区域,与三维Ising CFT中的已知值兼容。
A bstractWe study the conformal bootstrap for systems of correlators involving nonidentical operators. The constraints of crossing symmetry and unitarity for such mixed correlators can be phrased in the language of semidefinite programming. We apply this formalism to the simplest system of mixed correlators in 3D CFTs with a ℤ2 global symmetry. For the leading ℤ2-odd operator σ and ℤ2-even operator ϵ, we obtain numerical constraints on the allowed dimensions (Δσ, Δϵ) assuming that σ and ϵ are the only relevant scalars in the theory. These constraints yield a small closed region in (Δσ, Δϵ) space compatible with the known values in the 3D Ising CFT.
