Anomalous WWZ couplings and K L → μ + μ −
We study contributions to KL → μμ from anomalous WWZ interactions. There are, in general, seven anomalous couplings. Among the seven anomalous couplings, only two of them contribute significantly. The others are suppressed by factors like m2s/M 2 W , m 2 d/M 2 W , or m 2 K/M 2 W . Using the experimental data on KL → μμ, we obtain strong bounds on the two anomalous couplings. Typeset using REVTE...
متن کاملB → X s μ + μ − in Technicolor with Scalars
We compute the flavor changing neutral current process B → Xsμ +μ− in technicolor models with scalars. We find that the branching ratio can be enhanced relative to that of the Standard Model by as much as 60%. The full parameter space of the model is consistent with the present CLEO and CDF exclusive limits. However, the viability of the model could soon be tested since the decay signals are ex...
متن کاملB s → μ + μ − decay in the Randall - Sundrum model
Abstract We investigate theBs → μ+μ− decay in the presence of a light stabilized radion, a key ingredient of the Randall-Sundrum model. The branching ratio BR(Bs → μ+μ−) in the standard model is found to be 3.65 × 10−9 (two order smaller than the experimental upper bound) and raises the hope for some new physics which can explain the deficit. We found that in this brane world model for a reason...
متن کاملLepton Polarization in the Decays B → X s μ + μ − and B → X s τ + τ −
The effective Hamiltonian for the decay b → s l + l − predicts a characteristic polarization for the final state lepton, which can serve as an important test of the underlying theory. The lepton polarization has, in addition to a longitudinal component P L , two orthogonal components P T and P N , lying in and perpendicular to the decay plane which are proportional to m l /m b , and therefore s...
متن کاملExploiting the symmetries of P and S wave for B → K ∗ μ + μ −
After summarizing the current theoretical status of the four-body decay B → K∗(→ Kπ)μ+μ−, we apply the formalism of spin-symmetries to the full angular distribution, including the S-wave part involving a broad scalar resonance K∗ 0 . While we recover in the P-wave sector the known relation between the angular observables P (′) i , we find in the S-wave sector two new relations connecting the co...
