Deploying heavier η meson states: Configurational entropy hybridizing AdS/QCD

Configurational Entropy Revisited

1548 Journal of Chemical Education • Vol. 84 No. 9 September 2007 • www.JCE.DivCHED.org Entropy change is categorized in some prominent general chemistry textbooks as being either positional (configurational) or thermal. Positional entropy focuses on the number of positions in space that can be occupied by the molecules of a system. Then, to the extent that more positions exist after a process ...

The η ′ g ∗ g ( ∗ ) Vertex Including the η ′ - Meson Mass

The η ′ g * g (*) effective vertex function (EVF) is calculated in the QCD hard-scattering approach, taking into account the η ′-meson mass. We work in the approximation in which only one non-leading Gegen-bauer moment in both the quark-antiquark and gluonic light-cone distribution amplitude for the η ′-meson is kept. The EVF with one off-shell gluon is shown to have the form F η ′ g * g (q 2 1...

Configurational entropy of hard spheres

We numerically calculate the configurational entropy Sconf of a binary mixture of hard spheres, by using a perturbed Hamiltonian method trapping the system inside a given state, which requires less assumptions than the previous methods [R.J. Speedy, Mol. Phys. 95, 169 (1998)]. We find that Sconf is a decreasing function of packing fraction φ and extrapolates to zero at the Kauzmann packing frac...

Measurement of exclusive D meson decays to η and η ′ final states and SU ( 3 ) amplitude analysis

Using 281 pb−1 of data collected with the CLEO-c detector, we present new measurements of Cabibbo-suppressed decays of D0 and D+ mesons to η and η′ final states. We make first observations of D0 → η′π0, ηη, ηη′, and ηπ+π−, and find evidence for D+ → ηπ+π0, D+ → η′π+π0 and D0 → η′π+π−. We also report on improved measurements of D0 → ηπ0, D+ → ηπ+ and D+ → η′π+. Using the measured two-body Cabibb...
