Two-Body Cabibbo-Suppressed Charmed Meson Decays
Cheng-Wei Chiang, Zumin Luo, Jonathan L. Rosner
Singly-Cabibbo-suppressed decays of charmed particles governed by the quark subprocesses and are analyzed using a flavor-topology approach, ba…
Light Gluino and the Running of alpha_s
Cheng-Wei Chiang, Zumin Luo, Jonathan L. Rosner
A gluino in the mass range 12--16 GeV combined with a light (2--5.5 GeV) bottom squark, as has been proposed recently to explain an excess of b quark hadroproduction, would affect…
and the tree amplitude in
Cheng-Wei Chiang, Zumin Luo, Jonathan L. Rosner
The recently-observed decay is expected to proceed mainly by means of a tree amplitude in the factorization limit: , ${(W^+)}^* \to D_s^+…
Higgs Boson Decay into Hadronic Jets
Edmond L. Berger, Cheng-Wei Chiang, Jing Jiang +2
The remarkable agreement of electroweak data with standard model (SM) predictions motivates the study of extensions of the SM in which the Higgs boson is light and couples in a sta…
