Less suppressed mu-e-gamma and tau-mu-gamma loop amplitudes and extra dimension theories
Bo He, T. P. Cheng, Ling-Fong Li
When mu-e-gamma (or tau-mu-gamma) loop involves a vector boson, the amplitude is suppressed by more than two powers of heavy particle masses. However we show that the scalar boson…
Heavy particle electroweak loop effects in extra-dimensional models with bulk neutrinos
T. P. Cheng, Ling-Fong Li
One way to detect the presence of new particles in theories beyond the standard model is through their contribution to electroweak loop effects. We comment on the importance of a c…
Further Comments on a Vanishing Singlet Axial Vector Charge
T. P. Cheng, N. I. Kochelev, V. Vento
The recent suggestion of a vanishing flavor-singlet axial charge of nucleon due to a nontrivial vacuum structure is further amplified. A perturbative QCD discussion, applicable for…
Instantons and the singlet-coupling in the chiral quark model
T. P. Cheng, Ling-Fong Li
Chiral quark model with a broken-U(3) flavor symmetry can be interpreted as the effective theory of the instanton-dominated non-perturbative QCD. This naturally suggests the possib…
Non-perturbative QCD spin studies
T. P. Cheng, Ling-Fong Li
A whole class of non-perturbative QCD studies, e.g. the instanton models, chiral quark models, etc. indicates that the effective degrees of freedom for the physics in the low Q^(2)…
Why Naive Quark Model Can Yield a Good Account of the Baryon Magnetic Moments
T. P. Cheng, Ling-Fong Li
The chiral quark model suggests that the baryon quark-sea is negatively polarized. This modifies the spin structure as given by the naive quark model and agrees with experimental d…
