The relation between climatic parameters (relative air humidity) and the water activity of the Urmia Sea water determines the possible maximum evaporation of the lake. Using the Pitzer thermodynamic approach, the activity of the Urmia Lake water during evaporation was calculated and compared to the present relative air humidity above the water. Present climatic conditions allow the Urmia Sea wa...

Abstract In the present work, form factors of $$B_{(s)}$$ B ( s ) to light P-wave tensor mesons ( $$a_2(1320)$$ a 2 1320 , $$K^*_2(1430)$$ K...

In this work, we investigated the mixing between strange axial vector mesons K1(1270) and K1(1400) by using QCD Sum Rules approach. Since these states couple to same interpolating currents, defined them in terms of orbital angular momentum eigen K1A K1B. By tensor currents which are almost purely coupling K1B, then employing orthogonality physical states, obtained an analytical expression for K...

A partial wave analysis is presented of J/ψ → φππ and φKK from a sample of 58M J/ψ events in the BES II detector. The f0(980) is observed clearly in both sets of data, and parameters of the Flatté formula are determined accurately:M = 965± 8 (stat) ±6 (syst) MeV/c, g1 = 165± 10± 15 MeV/c, g2/g1 = 4.21± 0.25± 0.21. The φππ data also exhibit a strong ππ peak centred at M = 1335 MeV/c. It may be f...

It is shown that the list of unusual mesons planned for a careful study in photoproduction can be extended by the exotic states X(1600) with I(J) = 2(2) which should be looked for in the ρρ decay channels in the reactions γN → ρρN and γN → ρρ∆. The full classification of the ρρ states by their quantum numbers is presented. A simple model for the spin structure of the γp → f2(1270)p, γp → a2(132...

The ρρ interaction in the hidden gauge formalism and the f 0 (1370) and f 2 (1270) resonances. Abstract We have studied the interaction of vectors mesons within the hidden gauge formalism and applied it to the particular case of the ρρ interaction. We find a strong attraction in the isospin, spin channels I,S=0,0 and 0,2, which is enough to bind the ρρ system. We also find that the attraction i...

The TCOF1 gene product, treacle, responsible for the craniofacial disorder Treacher Collins syndrome, has been predicted to be a member of a class of nucleolar phosphoproteins based on its primary amino acid sequence. Treacle is a low complexity protein with ten repeating units of acidic and basic residues, each of which contains a large number of putative casein kinase 2 and protein kinase C p...
