Pion masses in quasiconformal gauge field theories
arXiv:0901.3528 · doi:10.1103/PhysRevD.79.057903
Abstract
We study modifications to Weinberg-like sum rules in quasiconformal gauge field theories. Beyond the two Weinberg sum rules and the oblique S parameter we study the pion mass and the X parameter. Especially, we evaluate the pion mass for walking technicolour theories, in particular also minimal walking technicolour, and find contributions of the order of up to several hundred GeV.
