Analysis of in light-front quark model and chiral perturbation theory of order
Chuan-Hung Chen, Chao-Qiang Geng, Chong-Chung Lih
Within the frameworks of the light-front quark model (LFQM) and chiral perturbation theory (ChPT) of , we reevaluate the form factors of the transition. We use…
Flavors and Phases in Unparticle Physics
Chuan-Hung Chen, Chao-Qiang Geng
Inspired by the recent Georgi's unparticle proposal, we study the flavor structures of the standard model (SM) particles when they couple to unparticles. At a very high energy scal…
U-boson and the HyperCP exotic events
Chuan-Hung Chen, Chao-Qiang Geng, Chung-Wen Kao
We show that the very light spin-1 gauge U-boson of the extra gauge model in the framework of the supersymmetric standard model extension can be a good candidate of the new…
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,…
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…
