Best Fit

Stevenson's principle of minimal sensitivity is used in renormalizing radiative corrections to hyperfine splittings, leptonic and hadronic decay widths, and electric-dipole transition rates. Numerical values for these quantities are presented for the charmonium and bottomonium systems, enlisting several nonrelativistic phenomenological potential models to determine the best fit to the experimental data. It is shown that good results may be obtained within a single model in which the value of ΛQCD is calculated and kept constant for all predictions within that model.

In this paper we revisited phenomenological potentials. We studied S-wave heavy quarkonium spectra by two potential models. The first one is power potential and the second one is logarithmic potential. We calculated spin averaged masses, hyperfine splittings, Regge trajectories of pseudoscalar and vector mesons, decay constants, leptonic decay widths, two-photon and two-gluon decay widths, and some allowed M1 transitions. We studied ground and 4 radially excited S-wave charmonium and bottomonium states via solving nonrelativistic Schrödinger equation. Although the potentials which were studied in this paper are not directly QCD motivated potential, obtained results agree well with experimental data and other theoretical studies.

Phenomenological Potential

A simple phenomenological potential model is suggested to describe the interaction between the constituent quarks of meson systems. Taking the spin-dependence terms in consideration modifies some previous potential models. The resonance masses and the leptonic decay widths of [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text] mesons are calculated using the nonrelativistic wave equation. A comparison between the present calculations and the available experimental results are given.

This contribution reviews briefly some aspects of the electronic spectra and circular dichroism of the series of structures I, where X = C or O and n = 0, 1, or 2, and exemplifies some of the general principles outlined by Professor Mason in his introduction. To provide a qualitative interpretation of the results, the coupling between the component π chromophores will be analysed by the simplest Hückel m. o. theory. First, let us remind ourselves of the behaviour of a 1, 3-diene (I; n = 0, X = C). Figure 1 shows diagrammatically the change in energy of the π orbitals as the mole­cule is rotated about the 2, 3 single bond from the conformation where the two double bonds are at right angles to one another, on the left, to the one where they are in the same plane, on the right. Dienes with an intermediate angle of twist constitute a helical system that leads to a magnetic as well as an electric dipole transition moment. The right-handed helix, in the cisoid (IV) or transoid (V) arrangement, produces a positive rotational strength (Charney, Ziffer & Weiss (1965).
