研究了保宇称三维连续函数管中应力张量四点函数的共形引导。为了建立自举方程,我们分析了共形对称性,置换对称性和守恒对应力张量4点函数的约束,并确定了一组非冗余的交叉方程。研究这些方程的数值半定优化,我们计算边界上的中心电荷的应力张量3点函数中的独立系数的函数。在没有额外假设的情况下,这些边界数值上再现了共形碰撞边界,并给出了中心电荷的一般下界。我们还研究了标量,自旋-2,和自旋-4的光谱上的中心电荷绑定的间隙的效果。我们发现一般的上限,这些差距,以及更严格的限制,应力张量3点函数系数的理论与适度的差距。当差距的领导标量或自旋2运营商是足够大,以排除大N理论,我们也得到了上界的中心电荷,从而找到紧凑的允许区域。最后,在已知临界三维伊辛模型的低能谱和中心电荷的条件下,确定了它的应力张量三点函数,并导出了它的奇宇称标量的一个界.
We study the conformal bootstrap for 4-point functions of stress tensors in parity-preserving 3d CFTs. To set up the bootstrap equations, we analyze the constraints of conformal symmetry, permutation symmetry, and conservation on the stress-tensor 4-point function and identify a non-redundant set of crossing equations. Studying these equations numerically using semidefinite optimization, we compute bounds on the central charge as a function of the independent coefficient in the stress-tensor 3-point function. With no additional assumptions, these bounds numerically reproduce the conformal collider bounds and give a general lower bound on the central charge. We also study the effect of gaps in the scalar, spin-2, and spin-4 spectra on the central charge bound. We find general upper bounds on these gaps as well as tighter restrictions on the stress-tensor 3-point function coefficients for theories with moderate gaps. When the gap for the leading scalar or spin-2 operator is sufficiently large to exclude large N theories, we also obtain upper bounds on the central charge, thus finding compact allowed regions. Finally, assuming the known low-lying spectrum and central charge of the critical 3d Ising model, we determine its stress-tensor 3-point function and derive a bound on its leading parity-odd scalar.
