Partially Strong WW Scattering
Kingman Cheung, Cheng-Wei Chiang, Tzu-Chiang Yuan
What if only a light Higgs boson is discovered at the CERN LHC? Conventional wisdom tells us that the scattering of longitudinal weak gauge bosons would not grow strong at high ene…
Unparticle effects in photon-photon scattering
Chun-Fu Chang, Kingman Cheung, Tzu-Chiang Yuan
Elastic photon-photon scattering can only occur via loop diagrams in the standard model and is naturally suppressed. Unparticle can induce tree-level photon-photon scattering throu…
Higgs Boson Decays into Single Photon plus Unparticle
Kingman Cheung, Chong Sheng Li, Tzu-Chiang Yuan
The decay of the standard model Higgs boson into a single photon and a vector unparticle through a one-loop process is studied. For an intermediate mass Higgs boson, this single ph…
Hidden Fermion in Stueckelberg Z' Models as Milli-charged Dark Matter
Kingman Cheung, Tzu-Chiang Yuan
The hidden Stueckelberg Z' model is augmented by a pair of Dirac fermions. If the Z' has a coupling strength comparable to weak scale coupling, one can show that this hidden fermio…
Collider signatures for unparticle
Kingman Cheung, Wai-Yee Keung, Tzu-Chiang Yuan
We summarize the works presented in Refs. \cite{1,2} on collider phenomenology of the unparticle physics associated with an exact scale invariant sector possessing a non-trivial in…
Bottomed Analog of Z+(4433)
Kingman Cheung, Wai-Yee Keung, Tzu-Chiang Yuan
The newly observed resonance by BELLE is believed to be a tetraquark bound state made up of . We propose the bottomed analog of this bound state,…
