Interpretation of the Theta+ as an isotensor pentaquark with weakly decaying partners
Simon Capstick, Philip R. Page, Winston Roberts
The Theta+(1540), recently observed at LEPS, DIANA and CLAS, is hypothesized to be an isotensor resonance. This implies the existence of a multiplet where the Theta++, Theta+ and T…
Polarization and `Model Independent' Extraction of from and
Winston Roberts
We briefly discuss the predictions of the heavy quark effective theory for the semileptonic decays of a heavy pseudoscalar to a light one, or to a light vector meson. We point out…
On the Monopole Model Of Form Factors for Heavy Meson Decays
Winston Roberts
A pole model for the form factors describing heavy to light meson transitions is constructed, and the results compared with the predictions of the heavy quark effective theory (HQE…
Strong Decays Of Heavy Hadrons In HQET
W. Roberts
We discuss the application of the tensor formalism of HQET to the strong decays of heavy hadrons. We treat both meson and baryon decays, and note that all of our results are in agr…
A Model For Two-Pion Photoproduction Amplitudes
W. Roberts, A. Rakotovao
We present a brief discussion of the general form of the amplitude that describes the two-pion photoproduction process. We outline an effective Lagrangian method that we are using…
Meson Decays In A Quark Model
W. Roberts, B. Silvestre-Brac
A recent model of hadron states is extended to include meson decays. We find that the overall success of the model is quite good. Possible improvements to the model are suggested.
