摘要: Within the framework of the heavy quark effective theory, QCD sum rules are used to calculate the masses of p-wave ¯cs states. The results for 0+ and 1+ states with the angular momentum of the light component jl = 1/2 are consistent with the experimental values for Ds(2317) and Ds(2457), respectively.

摘要: In the framework in which supersymmetry is used for understanding fermion masses rather than stabilizing the electroweak scale, we elaborate on the phenomenological analysis for the neutrino physics. A relatively large sin #18;13 ≃ 0.13 is naturally obtained. The model further predicts vanish-ingly small CP violation in neutrino oscillations. While the high scale supersymmetry genericallyresults in a Higgs mass of about 141 GeV, our model reduces this mass to 126 GeV via introducingSU(2)L triplet fields which make the electroweak vacuum metastable (with a safe lifetime) and also contribute to neutrino masses.
