Through the composite spectrum of the mass-deformed theory on the lattice, we investigate the physics near the lower edge of the conformal window in SU(3) gauge theory with N_f fundamental fermions. A possible candidate is found for the walking technicolor theory, which shows consistency with the slowly running coupling, spontaneous chiral symmetry breaking, and large anomalous dimension, the properties for the successful technicolor theory to replace the Higgs sector of the standard model. The flavor singlet scalar spectrum is investigated for the test whether the 125 GeV Higgs could be accommodated in the theory.
The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
