The North Ecliptic Pole Supercluster
We have used the ROSAT All-Sky Survey to detect a known supercluster at z = 0.087 in the North Ecliptic Pole region. The X-ray data greatly improve our understanding of this supercluster’s characteristics, approximately doubling our knowledge of the structure’s spatial extent and tripling the cluster/group membership compared to the optical discovery data. The supercluster is a rich structure c...

متن کاملClassification of the scalar mesons: a strange pole expedition into charm and beauty territory
The classification of scalar and vector mesons is reviewed within the framework of the Resonance-Spectrum Expansion (RSE). This method allows a simple and straightforward description of non-exotic meson-meson scattering, incorporating the effects of quark confinement and OZI-allowed decay in a fully nonperturbative way. Results for resonances and bound states are compared to experiment, on the ...
