Measurement of B-0 -> J/psi eta((')) and constraint on the eta - eta ' mixing angle

. The results for the branching fractions are: B(B-0 -> J/psi eta) = (12.3 +/-(1.8)(1.7)+/- 0.7) x 10(-6) and B(B-0 -> J/psi eta') < 7.4 x 10(-6) at 90% confidence level. The eta-eta' mixing angle is const...

Propene complexes of molybdenum and tungsten stabilized by intramolecular coordination of the 1-(quinol-8-yl)indenyl ligand

We report herein a new class of mixed propene-indenyl complexes of molybdenum [{eta(5):kappa N-1-(C9H6N)C9H6}(eta(2)-C3H6)M(CO)(2)][BF4] (M = Mo, W) were obtained in nearly quantitative yields by the protonation of the ...

Calculations of eta-nuclear quasi-bound states in few-body systems

We report on our Stochastic Variational Method (SVM) calculations of eta of the p-shell nucleus Li-6. The eta N potentials used were constructed from eta N) resonance. We found that eta Li-6 is bound in the eta...

Coupled channels approach to eta N and eta ' N interactions

We present a coupled channels separable potential approach to eta N and eta'N interactions using a chiral symmetric interaction kernel. The s-wave pi N amplitudes and pi(-) p induced total cross sections are reproduced satisfactorily in a br...
