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...
INTRODUCTION AND OBJECTIVE Deoxynivalenol (DON) is one of several mycotoxins produced by certain Fusarium species that frequently infect wheat, corn, rice, oats, barley and other grains in the field or during storage. Guilan, Golestan and Mazandaran areas are located in the North Iran with favorite conditions for Fusarium growth. DON affects animal and human health causing vomiting, acute tempo...
The suitability of a liposomal form of hydrophobic nonsulfonated meso-tetraphenyl porphyrin (TPP) for the photodynamic therapy of tumors was investigated. TPP was solubilized in small unilamellar lipid vesicles prepared by extrusion on a LIPOSOFAST apparatus. These samples were studied by laser-excited time resolved luminescence and triplet-triplet absorption spectroscopy. In this lipid environ...
It is shown that the list of unusual mesons planned for a careful study with the photon facility at JLAB 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)...
abstract An extensive spectrum of light non-strange q ¯ q states up to a mass of 2400 MeV has emerged from Crystal Barrel and PS172 data on ¯ pp → Resonance → A + B in 17 final states. These data are reviewed with detailed comments on the status of each resonance. For I = 0, C = +1, the spectrum is complete and very secure. Six 'extra' states are identified. Four of them have I = 0, C = +1 and ...
