Query: Flavor and electroweak symmetry breaking at the TeV scale   We present a unified picture of flavor and electroweak symmetry breaking at
the TeV scale. Flavor and Higgs bosons arise as pseudo-Goldstone modes in a
nonlinear sigma model. Explicit collective symmetry breaking yields stable
vacuum expectation values and masses protected at one loop by the little-Higgs
mechanism. The coupling to the fermions through a Yukawa lagrangian with a U(1)
global flavor symmetry generates well-definite mass textures that correctly
reproduce the mass hierarchies and mixings of quarks and leptons. The model is
more constrained than usual little- Higgs models because of bounds on weak and
flavor physics. The main experimental signatures testable at the LHC are a
rather large mass mh0 = 317+/-80 GeV for the (lightest) Higgs boson and a
characteristic spectrum of new bosons and fermions with masses around the TeV
scale.
