Open charm meson spectroscopy: Where to place the latest piece of the puzzle

We discuss how to classify the $c{\bar s}$ meson $D_{sJ}(3040)$ recently discovered by the BaBar Collaboration. We consider four possible assignments, together with signatures useful to distinguish among them.Comment: RevTeX, 5 pages, 1 eps figur

Anomalous AV^*V vertex function in the soft-wall holographic model of QCD

I consider the three-point function of two vector and one axial-vector currents. In the kinematic configuration in which one of the two vector currents corresponds to an on-shell soft photon, such a vertex is described in QCD by two functions, $w_L$ and $w_T$. After reviewing the properties of these functions in QCD, I describe the result obtained using the soft-wall holographic model of QCD with the addition of the Chern-Simons term and I compare it with the QCD outcome. I also discuss a relation, proposed by Son and Yamamoto, that connects $w_L$ and $w_T$ to the two-point functions $\Pi_{VV}$ and $\Pi_{AA}$.Comment: LaTeX, 8 pages.

Weak Decays of Heavy Quarks

We review some aspects of weak decays of hadrons containing one heavy quark. The main emphasis is on $B$ physics, in particular in the framework of the Heavy Quark Effective Theory.Comment: LaTex, 48 pages, 4 figures; uses psfig, sprocl.sty.
