An Analysis of the Decay $B \rightarrow D^* X \ell \bar\nu_\ell$ with Predictions from Heavy Quark and Chiral Symmetry

, 1992
This paper considers the implications of the heavy quark and chiral symmetries for the semi-leptonic decay $B \rightarrow D^* X \ell \bar \nu_\ell$. The general kinematic analysis for decays of the form {\sl pseudoscalar meson $\rightarrow$ vector meson $

On Scalar Meson Dominance in Semi- and Non-Leptonic Weak Pseudoscalar Meson Decays

, 2005
Aspects of Scalar Meson Dominance in semi- and non-leptonic weak pseudoscalar meson decays are shortly discussed on the basis of the Quark-Level Linear Sigma Model.Comment: 5 pages, no figures, contribution to XI Int. Conf.

Comparing symmetry restoration trends for meson masses and mixing angles in the QCD-like three quark flavor models

, 2013
We are computing the modifications for the scalar and pseudoscalar meson masses and mixing angles due to the proper accounting of fermionic vacuum fluctuation in the framework of the generalized 2+1 flavor quark meson model and the Polyakov loop ...

Branching ratios of Bc Meson Decaying to Pseudoscalar and Axial-Vector Mesons

, 2009
We study Cabibbo-Kobayashi-Maskawa (CKM) favored weak decays of Bc mesons in the Isgur-Scora-Grinstein-Wise (ISGW) quark model. We present a detailed analysis of the Bc meson decaying to a pseudoscalar meson (P) and an axial-vector meson (A).

Implications on $\eta$-$\eta'$-glueball mixing from $B_{d/s} \to J/\Psi \eta^{(')}$ Decays

, 2012
We point out that the recent Belle measurements of the $B_{d/s} \to J/\Psi \eta^{(')}$ decays imply large pseudoscalar glueball contents in the $\eta^{(\prime)}$ meson.

Study of the production mechanism of the eta meson by means of analysing power measurements

, 2006
Information about the production mechanism of the eta meson in proton-proton collisions can be inferred by confronting the experimental studies on the analysing power for the p(pol)p --> pp eta reaction with the theoretical predictions of this observable.
