Line shapes in Υ(5S) \to B^{()} \bar{B}^{()}πwith Z(10610) and Z(10650) using effective field theory

Thomas Mehen, Josh Powell

The Belle collaboration recently discovered two resonances, $Z_{b} (10610)$ and $Z_{b} (10650)$ --- denoted $Z_{b}$ and $Z_{b}^{'}$ --- in the decays $Υ (5 S) \to Υ (n S) π^{+} π^{-}$ for $n$ = 1…

Scaling Dimensions in AdS/QCD and the Gluon Field Strength Propagator

Joshua W. Powell

We derive the scaling dimension of antisymmetric tensor operators in the boundary theory of the AdS/CFT correspondence using a functional integral representation of the boundary-to…

Heavy Quark Symmetry Predictions for Weakly Bound B-Meson Molecules

Thomas Mehen, Joshua W. Powell

Recently the Belle collaboration discovered two resonances, Zb(10610) and Zb(10650), that lie very close to the B\bar{B}^* and B^*\bar{B}^* thresholds, respectively. It is natural…
