Electroweak symmetry breaking and extra dimensions
Hsin-Chia Cheng
The electroweak symmetry may be broken by a composite Higgs which arises naturally as a bound state of the top quark if the standard model gauge fields and fermions propagate in ex…
Bounds on Universal Extra Dimensions
Thomas Appelquist, Hsin-Chia Cheng, Bogdan A. Dobrescu
We show that the bound from the electroweak data on the size of extra dimensions accessible to all the standard model fields is rather loose. These "universal" extra dimensions cou…
Minimal electroweak symmetry breaking model in extra dimensions
Hsin-Chia Cheng
We show that if the Standard Model gauge fields and fermions propagate in extra dimenions, a composite Higgs field with the correct quantum number can arise naturally as a bound st…
Self-Breaking of the Standard Model Gauge Symmetry
Nima Arkani-Hamed, Hsin-Chia Cheng, Bogdan A. Dobrescu +1
If the gauge fields of the Standard Model propagate in TeV-size extra dimensions, they rapidly become strongly coupled and can form scalar bound states of quarks and leptons. If th…
Electroweak symmetry breaking by extra dimensions
Hsin-Chia Cheng, Bogdan A. Dobrescu, Christopher T. Hill
Electroweak symmetry breaking may be naturally induced by the observed quark and gauge fields in extra dimensions without a fundamental Higgs field. We show that a composite Higgs…
