Discovering Walking Technicolor at LHC and Lattice
Abstract
Walking technicolor, having a large anomalous dimension γm 1 and approximate scale symmetry, predicts Technidilaton, a light composite Higgs as a pseudo-Nambu-Goldstone boson of the approximate scale symmetry, which can be identified with the 125 GeV boson discovered at LHC. I will describe how such a weakly coupled light composite scalar can be dynamically realized in the strongly coupled dynamics, and can be fit to the current data at LHC, based on the ladder-like computation and the holographic one. I will also present results of our lattice collaboration (LatKMI Collaboration) searching for a walking theory and a light flavor-singlet scalar bound state in large Nf QCD.
