JHEP 0208:019 (2002)
Shows that the fundamental group of theory space determines all relevant classical physics in the low-energy theory of Little Higgs models, providing a systematic method for constructing theory spaces with any desired particle content and potential.
JHEP 0208:021 (2002)
Introduces the minimal theory-space construction for a Little Higgs model, where the Higgs is a pseudo-Goldstone boson protected from quadratic divergences by collective symmetry breaking. Predicts new TeV-scale partners for the top quark, gauge bosons, and scalars, with the entire Higgs potential generated by the top Yukawa coupling.
JHEP 0208:020 (2002)
Works out the collider phenomenology and dark matter implications of the Little Higgs mechanism, predicting light Higgs doublets accompanied by new weak triplet and singlet scalars, heavy TeV-scale particles with distinctive decay signatures, and a new WIMP dark matter candidate from a discrete geometric symmetry.
