A solution to the hierarchy problem from an almost decoupled hidden sector within a classically scale invariant theory
Robert Foot, Archil Kobakhidze, Kristian L. McDonald +1
If scale invariance is a classical symmetry then both the Planck scale and the weak scale should emerge as quantum effects. We show that this can be realized in simple scale invari…
Comment on ``New Physics Contributions to the Lifetime Difference in mixing''
Chuan-Hung Chen, Chao-Qiang Geng, Soo-Hyeon Nam
We find that in the nonmanifest left-right (LR) model, an important LR mixing effect was not considered in the paper by E. Golowich, S. Pakvasa, and A. Petrov, Phys. Rev. Lett. 98,…
Neutrino mass in radiatively-broken scale-invariant models
Robert Foot, Archil Kobakhidze, Kristian. L. McDonald +1
Scale invariance may be a classical symmetry which is broken radiatively. This provides a simple way to stabilize the scale of electroweak symmetry breaking against radiative corre…
Unparticle phase effects
Chuan-Hung Chen, Chao-Qiang Geng
Unparticles proposed by Georgi carry CP conserving phases in their propagators. We demonstrate that these peculiar phases have an important impact on CP violation. Without includin…
Unparticle physics on direct CP violation
Chuan-Hung Chen, Chao-Qiang Geng
The effects of the peculiar CP conserving phases in unparticle propagators are explored. We find that the phases have a great impact on CP-violation. We adopt the decays $B_{d}\to…
Study of Decays
Chuan-Hung Chen, Chao-Qiang Geng, Chong-Chung Lih +1
We examine the exclusive rare decays of with being the p-wave scalar meson and in the standard model. The form f…
