Theory of a Strongly Interacting Electroweak Symmetry Breaking Sector
R. Sekhar Chivukula, Michael J. Dugan, Mitchell Golden +1
In this review we discuss theories of the electroweak symmetry breaking sector in which the and interactions become strong at an energy scale not larger than a few TeV.
The Higgs Boson Width is Adjustable
R. Sekhar Chivukula, Michael J. Dugan, Mitchell Golden
We show that it is possible to construct models in which the width of the Higgs boson is arbitrary - either smaller or larger than a standard model Higgs boson of the same mass. Th…
Spinning Particles, Braid Groups and Solitons
Lee Brekke, Michael J. Dugan, Tom D. Imbo
We develop general techniques for computing the fundamental group of the configuration space of identical particles, possessing a generic internal structure, moving on a manifo…
The Implications of Naturalness in Effective Field Theory on the Masses of Resonances
Michael J. Dugan, Mitchell Golden
Many years ago Weinberg formulated a definition of ``naturalness'' for effective theories: if an effective theory is to make sense, coefficients must not change too much when the c…
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…
