Critical Constraints on Chiral Hierarchies
R. Sekhar Chivukula, Mitchell Golden, Elizabeth H. Simmons
We consider the constraints that critical dynamics places on models with a top quark condensate or strong extended technicolor (ETC). These models require that chiral-symmetry-brea…
A Comment on the Strong Interactions of Color-Neutral Technibaryons
R. Sekhar Chivukula, Andrew G. Cohen, Michael Luke +1
We estimate the cross section for the scattering of a slow, color-neutral technibaryon made of colored constituents with nuclei. We find a cross section of order cm…
Extended Technicolor Corrections to the Vertex
E. H. Simmons, R. S. Chivukula, S. B. Selipsky
Extended technicolor theories generate potentially large corrections to the $\Zbb$ vertex. These can be observed in current experiments at LEP.
The Phenomenology of a Hidden Symmetry Breaking Sector
R. Sekhar Chivukula, Mitchell Golden, Dimitrios Kominis +1
We calculate the production rate of gauge-boson pairs at the SSC in a model with a ``hidden'' electroweak symmetry breaking sector. We show that the signal of electroweak symmetry…
Electroweak Corrections in Technicolor Reconsidered
R. Sekhar Chivukula, M. Dugan, M. Golden
Radiative corrections to electroweak parameters in technicolor theories may be evaluated by one of two techniques: either one estimates spectral function integrals using scaled QCD…
Analyticity, Crossing Symmetry and the Limits of Chiral Perturbation Theory
R. Sekhar Chivukula, M. Dugan, M. Golden
The chiral Lagrangian for Goldstone boson scattering is a power series expansion in numbers of derivatives. Each successive term is suppressed by powers of a scale, , which mu…
