Penguin-like Diagrams from the Standard Model
Swee-Ping Chia
The Standard Model is highly successful in describing the interactions of leptons and quarks. There are, however, rare processes that involve higher order effects in electroweak in…
Decays of Z Boson into Pseudoscalar Meson Pair of Different Flavours
Swee-Ping Chia
We analyse the process Z-zero to M1 M2, where M1 and M2 are pseudoscalar mesons with quark contents of q1 q-bar and q-bar q2 respectively. At the quark level, the process-zero to q…
Rare Decays of K and B Mesons Revisited
Swee Ping Chia
The rare decays of mesons are higher order effects in weak interactions. The main contributions to such decay processes are from the Z-penguin, the photonpenguin and the box diagra…
Decays of Higgs Boson into Pseudoscalar Meson Pair of Different Flavours
Swee-Ping Chia
The flavour-changing quark-Higgs coupling does not arise at the tree level in the Standard Model. It is, however, induced by one-loop effects. In this paper, we present an exact ca…
Decay Constants of Pseudoscalar Mesons
Swee Ping Chia
For purely leptonic decays of pseudoscalar mesons, the decay rates are related to the product of the relevant weak interaction-based CKM matrix element of the constituent quarks on…
Semileptonic Decays of Pseudoscalar Mesons: A New Approach
Swee Ping Chia
Because quarks in hadronic states are subjected to strong QCD forces, it is not straight-forward to apply calculation obtained at the quark level to physical processes involving ha…
