    Wave Function Based Characteristics of Hybrid Mesons

    Full text link
    We propose some extensions of the quark potential model to hybrids, fit them to the lattice data and use them for the purpose of calculating the masses, root mean square radii and wave functions at the origin of the conventional and hybrid charmonium mesons. We treat the ground and excited gluonic field between a quark and an antiquark as in the Born-Oppenheimer expansion, and use the shooting method to numerically solve the required Schro¨\ddot{\textrm{o}}dinger equation for the radial wave functions; from these wave functions we calculate the mesonic properties. For masses we also check through a Crank Nichelson discretization. For hybrid charmonium mesons, we consider the exotic quantum number states with JPC=0+,1+ J^{PC} = 0^{+ -}, 1^{- +} and 2+2^{+ -}. We also compare our results with the experimentally observed masses and theoretically predicted results of the other models. Our results have implications for scalar form factors, energy shifts, magnetic polarizabilities, decay constants, decay widths and differential cross sections of conventional and hybrid mesons.Comment: 13 pages, 6 figures, Erratum is submitted to EPJ

    Tetrabutoxytitanium adduct formation in esterification reactions

    No full text
    Different mechanisms of the catalytic action of tetrabutoxytitanium in esterification and transesterification reactions are analyzed. New evidence is obtained in favor of the nonionic mechanism of ester formation catalysis by glycol-tetrabutoxytitanium adducts in esterification reactions. © 2009 Pleiades Publishing, Ltd
