Matrix elements of four-quark operators and ΔL=2 hyperon decays
C. Barbero, Ling-Fong Li, G. Lopez Castro +1
The study of neutrinoless double beta decays of nuclei and hyperons require the calculation of hadronic matrix elements of local four-quark operators that change the total charge b…
Consistency of Loop Regularization Method and Divergence Structure of QFTs Beyond One-Loop Order
Da Huang, Ling-Fong Li, Yue-Liang Wu
We study the problem how to deal with tensor-type two-loop integrals in the Loop Regularization (LORE) scheme. We use the two-loop photon vacuum polarization in the massless Quantu…
Introduction to Renormalization in Field Theory
Ling-Fong Li, Chongqing
A simple introduction of renormalization in quantum field theory is discussed. Explanation of concepts is emphasized instead of the technical details.
hyperon semileptonic decays
C. Barbero, Ling-Fong Li, G. Lopez Castro +1
We compute the rates of semileptonic B_A \to B_Bl^-l^- (l=e or μ) hyperon transitions in a model where intermediate states involve loops of baryons and a Majorana neutrino. These r…
Vector Goldstone Boson and Lorentz Invariance
Ling-Fong Li
Spontanous symmetry breaking usually gives spin 0 Goldstone bosons for the case of internal symmetries and spin 1/2 fermions for the supersymmetry. The spontaneous breaking of high…
Coupling Constant Unification in Extensions of Standard Model
Ling-Fong Li, Feng Wu
Unification of electromagnetic, weak, and strong coupling constants is studied in the extension of standard model with additional fermions and scalars. It is remarkable that this u…
