Composite Vector Mesons from QCD to the Little Higgs


الملخص بالإنكليزية

We review how the rho meson can be modeled in an effective theory and discuss the implications of applying this approach to heavier spin-one resonances. Georgis vector limit is explored, and its relationship to locality in a deconstructed extra-dimension is discussed. We then apply the formalism for rhos to strongly coupled theories of electroweak symmetry breaking, studying the lightest spin-one techni-rho resonances. Understanding these new particles in Little Higgs models can shed light on previously incalculable, ultraviolet sensitive physics, including the mass of the Higgs boson.
