Tau Decays into Kaons Typeset Using Revt E X

چکیده
Predictions for semi-leptonic decay rates of the lepton into two meson nal K ? ? + ; ? K 0 0 are derived. The hadronic matrix elements are expressed in terms of form factors, which can be predicted by chiral Lagrangians supplemented by informations about all possible low-lying resonances in the diierent channels. Isospin symmetry relations among the diierent nal states are carefully taken into account. The calculated branching ratios are compared with measured decay rates where data are available. We wish to dedicate this work to Roger Decker whose death at an early age is a great loss to his friends and to the physics community.

The decay ω(782) → 5π in chiral theory. Abstract The arguments are put forward that the many pion decays ω → 2π + 2π − π 0 and π + π − 3π 0 provide an ideal test site for testing the predictions of chiral models of the vector meson decays into many pions. Using the approach based on the Weinberg Lagrangian or, in a new language, the Lagrangian of hidden local symmetry added with the term induce...

We review current issues in exclusive semileptonic tau decays. We present the formalism of structure functions, and then discuss predictions for final states with kaons, for decays into four pions and for radiative corrections to the decay into a single pion.

The decays B0 → D∗+D∗−, B0 → DD and B0 → D+D− are studied in 9.7 × 106 Υ(4S) → BB̄ decays accumulated with the CLEO detector. We determine B(B0 → D∗+D∗−) = (9.9 −3.3 [stat.] ± 1.2 [syst.])×10 −4 and limit B(B0 → DD) < 6.3×10−4 and B(B0 → D+D−) < 9.4×10−4 at 90% confidence level (CL). We also perform the first angular analysis of the B0 → D∗+D∗− decay and determine that the CP -even fraction of t...

The coupling constants g ρηγ and g ωηγ are calculated using QCD sum rules method by studying the three point ρηγ and ωηγ correlation functions. A comparison of the results with the values of the coupling constants that are deduced from the experimentally measured decay widths of ρ → ηγ and ω → ηγ decays is performed.

We use QCD sum rules to calculate the hadronic matrix elements governing the rare decays B ! K` + ` ? and B ! K ` + ` ? induced by the avour changing neutral current b ! s transition. We also study relations among semileptonic and rare B ! K () decay form factors. The analysis of the invariant mass distribution of the lepton pair in B !
