Towers in [ω]ω and ωω

Natural Parity Resonances in the Ηπ + Π − and Ωω

Results of the ηππ and ωω final state partial wave analysis(PWA) are presented. The mass-independent and the mass-dependent PWA were performed. The ηππ system PWA results in the observation of the resonances in the J = 1, 3, 2 and 4 waves. The results of the ωω system PWA confirms the existence of the f2(1565) and f4(2050). The f2(1950) is observed. There is evidence for a f4(2300) meson.

Estimation of dibaryon (ΩΩ)Jπ=0+ yields at RHIC energies

The yields of dibaryon (ΩΩ)0+ in relativistic heavy ion collisions at three energies (AGS, SPS and RHIC energies) are calculated in the framework of statistical model. It’s yield at full RHIC energy, √ sNN = 200 GeV, is predicted by means of extrapolation. In the RHIC energy region (RHIC to full RHIC energies), it is in order of magnitude 10−4 − 10−3. The yields of hyperon Ω− and the ratios of ...

Generating transformation semigroups using endomorphisms of preorders, graphs, and tolerances

Let ΩΩ be the semigroup of all mappings of a countably infinite set Ω. If U and V are subsemigroups of ΩΩ, then we write U ≈ V if there exists a finite subset F of ΩΩ such that the subgroup generated by U and F equals that generated by V and F . The relative rank of U in ΩΩ is the least cardinality of a subset A of ΩΩ such that the union of U and A generates ΩΩ. We study the notions of relative...
