Phenomenology of iQuarkonium
Kingman Cheung, Wai-Yee Keung, Tzu-Chiang Yuan
Phenomenology of uncolored iquarks - hypothetical fermions charged under a new confining unbroken non-abelian gauge group as well as the standard electroweak gauge group - is inves…
Unparticle Phenomenology -- A Mini Review
Kingman Cheung, Wai-Yee Keung, Tzu-Chiang Yuan
We review some collider phenomenology of unparticle physics, including real emissions and virtual exchanges of unparticle. Existing experimental constraints from collider physics a…
PAMELA and dark matter
V. Barger, W. -Y. Keung, D. Marfatia +1
Assuming that the positron excess in PAMELA satellite data is a consequence of annihilations of cold dark matter, we consider from a model-independent perspective if the data show…
Spin Dependence of Dark Matter Scattering
Vernon Barger, Wai-Yee Keung, Gabe Shaughnessy
New experiments designed to discover a weakly interacting dark matter (DM) particle via spin dependent scattering can distinguish models of electroweak symmetry breaking. The plane…
Landau-Yang Theorem and Decays of a Z' Boson into Two Z Bosons
Wai-Yee Keung, Ian Low, Jing Shu
We study the decay of a Z' boson into two Z bosons by extending the Landau-Yang theorem to a parent particle decaying into two Z bosons. For a spin-1 parent the theorem predicts: 1…
Unparticle physics with broken scale invariance
Vernon Barger, Yu Gao, Wai-Yee Keung +2
If scale invariance is exact, unparticles are unlikely to be probed in colliders since there are stringent constraints from astrophysics and cosmology. However these constraints ar…
