C(X, Z) Revisited

The Higgs–photon–Z boson Coupling Revisited

We analyze the coupling of CP-even and CP-odd Higgs bosons to a photon and a Z boson in extensions of the Standard Model. In particular, we study in detail the effect of charged Higgs bosons in two–Higgs doublet models, and the contribution of SUSY particle loops in the minimal supersymmetric extension of the Standard Model. The Higgs–γZ coupling can be measured in the decay Z → γ+Higgs at e+e−...

Z 0 –Z 0 ′ and ordinary-exotic fermion mixings revisited using some

QUICKSELECT Revisited

We give an overview of the running time analysis of the random divide-and-conquer algorithm FIND or QUICKSELECT. The results concern moments, distribution of FIND’s running time, the limiting distribution, a stochastic bound and the key: a stochastic fixed point equation.

CP violating couplings in Z → 3 jet decays revisited

Possible CP violating effects in Z → 3 jet decays are investigated. The analysis assumes the presence of CP violating Zq ¯ qG couplings. The contribution of these couplings to the Z → q ¯ qG decay width is calculated for different cut algorithms, including nonzero quark masses. Various CP–odd observables are discussed and it is shown that their sensitivity can change significantly if one uses n...

cx-AMINO ACIDS IN CHILDREN

The determination of the total content of free a-amino acids in urine has become routine in paediatric practice in numerous diseases. Interest in aminoaciduria has greatly increased since it became known that many congenital metabolic disorders are accompanied by an increased excretion of free oc-amino acids in the urine (Paine, 1960; Woolf, 1961). The excretion of free a-amino-N is usually exp...
