Central Charge Bounds in 4D Conformal Field Theory | | Riccardo Rattazzi

14 Sep 2010 | | Abstract: | We derive model-independent lower bounds on the stress tensor central charge
C_T in terms of the operator content of a 4-dimensional Conformal Field Theory.
More precisely, C_T is bounded from below by a universal function of the
dimensions of the lowest and second-lowest scalars present in the CFT. The
method uses the crossing symmetry constraint of the 4-point function, analyzed
by means of the conformal block decomposition. | | Source: | arXiv, 1009.2725 | | Services: | Forum | Review | PDF | Favorites | |
