Abstract: Walking technicolor (WTC) theory attempts to realize electroweak symmetry breaking as the spontaneous chiral symmetry breakdown caused by the gauge dynamics with slowly varying gauge coupling constant and large mass anomalous dimension. Many-flavor QCD is one of the candidates for WTC. We focus on the SU(3) gauge theory with ten massless fermions in the fundamental representation, and investigate the running of the gauge coupling constant on the lattice. We observe evidence that this theory possesses an infrared fixed point.
