Walking techni-pions at LHC

Abstract: We calculate techni-pion masses of the walking technicolor (WTC), by explicitly evaluating nontrivial contributions from various possible chiral breaking sources in a concrete WTC setting of the one-family model. Our explicit computation of the mass and the coupling in this concrete model setting reveals that the techni-pions are on the order of several hundred GeV in the region to be discovered at LHC.
