我们对宇称守恒的三维共形场论中,涉及自旋为1的U(1)电流J与应力-能量张量T的关联函数混合系统进行了数值共形自举研究。我们发现了应力张量两点函数c_T的普适界限,这些界限数值上重现了关于⟨JJT⟩和⟨TTT⟩的共形对撞机界限,以及关于领先宇称偶和宇称奇标量算子维数的界限。在温和假设下,我们确定了O(2)矢量模型中⟨JJT⟩和⟨TTT⟩三点函数的值。其中⟨TTT⟩结果是新的,而⟨JJT⟩与文献中先前结果一致。
英文摘要
We perform a numerical conformal bootstrap study of the mixed system of correlation functions involving a spin-1 $\mathrm{U}(1)$ current $J$ and the stress-energy tensor $T$ in parity-preserving 3d CFTs. We find universal bounds on the stress-tensor two-point function $c_T$, which numerically reproduce the conformal collider bounds on $\langle JJT\rangle$ and $\langle TTT\rangle$, as well as bounds on the leading parity-even and parity-odd scalar operator dimensions. Under mild assumptions, we determine the values of the $\langle JJT\rangle$ and $\langle TTT\rangle$ three-point functions in the $\mathrm{O}(2)$ vector model. The $\langle TTT\rangle$ result is new and $\langle JJT\rangle$ is consistent with a previous result in the literature.
