 JHEP 10, 055 (2020) More on heavy-light bootstrap up to double-stress-tensor Yue-Zhou Li1,2,* & Hao-Yu Zhang3 1 Center for Joint Quantum Studies and Department of Physics, School of Science, Tianjin University, Tianjin, 300350, China 2 Department of Physics, McGill University, 3600 Rue University, Montréal, QC, Canada 3 George P. & Cynthia Woods Mitchell Institute for Fundamental Physics and Astronomy, Texas A&M University, College Station, TX, 77843, USA ABSTRACT We investigate the heavy-light four-point function up to double-stress-tensor, supplementing 1910.06357. By using the OPE coefficients of lowest-twist double-stress- tensor in the literature, we find the Regge behavior for lowest-twist double-stress-tensor in general even dimension within the large impact parameter regime. In the next, we perform the Lorentzian inversion formula to obtain both the OPE coefficients and anomalous dimensions of double-twist operators [ $\mathcal{O}$H  $\mathcal{O}$L]n,J with finite spin J in d = 4. We also extract the anomalous dimensions of double-twist operators with finite spin in general dimension, which allows us to address the cases that ∆L is specified to the poles in lowest-twist double-stress-tensors where certain double-trace operators [ $\mathcal{O}$L $\mathcal{O}$L]n,J mix with lowest-twist double-stress-tensors. In particular, we verify and discuss the Residue relation that deter- mines the product of the mixed anomalous dimension and the mixed OPE. We also present the double-trace and mixed OPE coefficients associated with ∆L poles in d = 6, 8. In the end, we turn to discuss CFT2, we verify the uniqueness of double-stress-tensor that is consistent with Virasoso symmetry. 【关闭窗口】
