Explaining the MiniBooNE Anomalous Excess via Leptophilic ALP-Sterile Neutrino Coupling
Chia-Hung Vincent Chang, Chuan-Ren Chen, Shu-Yu Ho +1
Recently, the MiniBooNE experiment at Fermilab has updated the results with increased data and reported an excess of electronlike events () in the neutrino…
Lepton Flavor Violating Decays of Neutral Higgses in Extended Mirror Fermion Model
Chia-Feng Chang, Chia-Hung Vincent Chang, Chrisna Setyo Nugroho +1
We perform the one-loop induced charged lepton flavor violating decays of the neutral Higgses in an extended mirror fermion model with non-sterile electroweak-scale right-handed ne…
Neutrino Masses in a 5D TeV Unification Model
Chia-Hung V. Chang, We-Fu Chang, John N. Ng
We study the generation of neutrino masses in the electroweak unified theory in spacetime. By appropriate orbifolding, the bulk symmetry…
B meson decays to baryons in the diquark model
Chia-Hung V. Chang, Wei-Shu Hou
We study B meson decays to two charmless baryons in the diquark model, including strong and electroweak penguins as well as the tree operators. It is shown that penguin operators c…
Probing for the Charm Content of and Mesons
Chia-Hung V. Chang, Wei-Shu Hou
A slow bump exists in the inclusive spectrum, while the softness of spectrum in decay is in strong contrast with expectations from colo…
Bulk Higgs Boson Decays in Brane Localized Gravity
Chia-Hung V. Chang, J. N. Ng
We embed the Standard Model in the Randall-Sundrum model of 5 dimensional brane localized gravity. The SM gauge and chiral fermion fields are restricted on the 4D visible brane whe…
Vector Quark Model and B to X_s gamma Decay
Chia-Hung V. Chang, Darwin Chang, Wai-Yee Keung
We study the meson radiative decay in the vector quark model. Deviation from the Standard Model arises from the non-unitarity of the charged current KM matrix and…
PQCD study of the and controversy in inclusive decays
Chia-Hung V. Chang, Darwin Chang, We-Fu Chang +2
We calculate the semileptonic branching ratio and the charm counting of inclusive meson decays using the perturbative QCD formalism. For the nonleptonic decays, we employ the m…
QCD Corrections to and Exclusive Decay
Chia-Hung V. Chang, Guey-Lin Lin, York-Peng Yao
The short distance QCD corrections to are calculated in the leading logarithmic approximation. The equivalence of operator basis reduction for S-matrix elements by using…
Three-Scale Factorization Theorem and Effective Field Theory
Chia-Hung V. Chang, Hsiang-nan Li
We develop a perturbative QCD factorization theorem which is compatible with effective field theory. The factorization involves three scales: an infrared cutoff of order $Λ_{\rm QC…
Solutions to the R_b, R_c and alpha_s puzzles by Vector Fermions
Chia-Hung V. Chang, Darwin Chang, Wai-Yee Keung
We propose two minimal extensions of Standard Model, both of which can easily accommodate the recent puzzling observations about the excess in , the deficit in and the d…
