Name: Kimmo Tuominen Institution: Department of Physics Title: Cold and hot phases of Technicolor Key Words: Electroweak symmetry breaking, Technicolor, Gauge/gravity duality Abstract: Phase diagram of cold SU(N) gauge theory, as a function of number of colors, flavors and fermion representations, implies phenomenologically viable Technicolor theories. Recently, such phase diagrams have been investigated using lattice calculations, and we briefly review the results. Then we show how application of AdS/CFT methods predict novel phase diagrams for these theories in finite temperature and discuss possible implications for the early Universe.
