چکیده
We present an asymptotic Padé-approximant estimate for the four-loop coefficients within the linear combination of correlators entering the recently calculated decay rate of a CP-odd Higgs boson, with an assumed mass m A = 100 GeV , into two gluons. All but one of these coefficients are shown to be determined for arbitrary m A from the known 3-loop-order rate by renormalization group methods. Asymptotic Padé-approximant estimates for these coefficients are all seen to be within 12% of their correct values. The four-loop term in the decay rate for m A = 100 GeV is estimated to be only 4.3% of its leading one-loop contribution.

The decay of Λ b → Σ (*) c πl¯ ν processes are calculated in the framework of heavy baryon chiral perturbation theory with help of the 1/N c expansion. The decay rate distributions over v · v ′ where v and v ′ are the 4-vector velocities of Λ b and Σ (*) c respectively, and over the pion and lepton energies are given. The decay branching ratios amount to about 1.21(0.971)% for Λ b → Σ c πl¯ ν a...

Rare Λb → Λl+l− decay is investigated in framework of general two Higgs doublet model, in which a new source of CP violation exists (model III). The polarization parameter, CP asymmetry and decay width are calculated. It is shown that CP asymmetry is a very sensitive tool for establishing model III. e-mail: [email protected] e-mail: [email protected]

Abstract We study CP violation in a multi-Higgs doublet model based on a S3 × Z3 horizontal symmetry. We consider two mechanisms for CP violation in this model: a) CP violation due to complex Yukawa couplings; and b) CP violation due to scalar-pseudoscalar mixings. We find that the predictions for ǫ/ǫ, CP violation in B decays and the electric dipole moments of neutron and electron are differen...
