Measurement of Z decays into lepton pairs.
. . We present measurements by the Mark II experiment of the ratios of the leptonic partial widths of the 2 boson to the hadronic partial width. The results are k = 0.037~~$~, & = 0.053’$:4: and k = 0.066~~:$$, in good agreement with the Standard Model prediction of 0.048. From the average leptonic width result, & = 0.053~~.~~~, we derive I’had = 1.56~~.~~ GeV. We find for the vector coupling c...
متن کاملAngular correlations of lepton pairs from vector boson and top quark decays in Monte Carlo simulations
We explain how angular correlations in leptonic decays of vector bosons and top quarks can be included in Monte Carlo parton showers, in particular those matched to NLO QCD computations. We consider the production of n pairs of leptons, originating from the decays of n electroweak vector bosons or of n top quarks, in the narrow-width approximation. In the latter case, the information on the n b...
متن کاملDecay of Pseudoscalars into Lepton Pairs and Large-Nc QCD
The theoretical study of the p0 and h decaying into lepton pairs and the comparison with the experimental rates [1,2] offers an interesting possibility to test our understanding of the long-distance dynamics of the standard model. These processes are dominated by the exchange of two virtual photons and it is therefore phenomenologically useful to consider the branching ratios normalized to the ...
متن کاملImplications of light-quark admixtures on charmonium decays into meson pairs
We argue that charmonium decays into meson pairs fall into two distinct classes: one that is under control of perturbative QCD and another one that is governed by a soft mechanism. We concentrate on a systematic analysis of J/ψ(Ψ) decays into a light pseudoscalar and a light vector meson and ηc decays into a pair of light vector mesons. These processes belong to the second class and are charact...
متن کاملFragmentation Functions for Lepton Pairs
We calculate the fragmentation function for a light quark to decay into a lepton pair to leading order in the QCD coupling constant. In the formal definition of the fragmentation function, a QED phase must be included in the eikonal factor to guarantee QED gauge invariance. We find that the longitudinal polarization fraction is a decreasing function of the factorization scale, in accord with th...
