The eta(η)-meson discovery came at a time when physicists realized that a new more adequate group theory classification of particles was needed. This eventually evolved into the quark theory. Since η-mesons decay very fast they can only be observed in final states of certain nuclear reactions...
Using 383 x 10(6) BBover pairs from the BABAR data sample, we report results for branching fractions of six charged B-meson decay modes, where a charged kaon recoils against a charmless resonance decaying to KKover* or etapipi final states with mass in the range (1.2-1.8) GeV/c2. We...

Using the most recent empirical data for the meson masses and total decay widths from Ref. [18], together with all the above considerations, one arrives at the decay width results shown in Table 1 for the six \eta ^{(\prime )}\rightarrow \pi ^0l^+l^- and \eta ^{\prime }\right...
In this section we describe the data on reactions (1) analyzed by COMPASS [9]. The unpolarized cross sections for both reactions depend on five kinematical variables. These are, for example, the total center of mass energy squared, the invariant mass of the produced meson pair, the square ...
