Meson Emission Model of Psi to N Nbar m Charmonium Strong Decays
T. Barnes, Xiaoguang Li, W. Roberts
In this paper we consider a sequential "meson emission" mechanism for charmonium decays of the type Psi -> N Nbar m, where Psi is a generic charmonium state, N is a nucleon and m i…
Hyperfine Mixing and the Semileptonic Decays of Double-Heavy Baryons in a Quark Model
W. Roberts, Muslema Pervin
The semileptonic decays of the lowest-lying double-heavy baryons is treated in a quark model. For the , hyperfine mixing in the spin wave function leaves the total rate for…
Semileptonic Decays of Heavy Lambda Baryons in a Quark Model
Muslema Pervin, Winston Roberts, Simon Capstick
The semileptonic decays of Lambda_c and Lambda_b are treated in the framework of a constituent quark model. Both nonrelativistic and semirelativistic Hamiltonians are used to obtai…
Polarization Observables in
W. Roberts
We explore some of the rich structure of the polarization observables recently developed for processes like and in the framework of a specific model…
A Phenomenological Lagrangian Approach to Two Kaon Photoproduction and Pentaquark Searches
W. Roberts
We examine cross sections for the processes in the framework of a phenomenological Lagrangian. We include contributions from and resonances up to spin 3/2…
Radiative Transitions in Heavy Mesons in a Relativistic Quark Model
J. L. Goity, W. Roberts
The radiative decays of , , and other excited heavy mesons are analyzed in a relativistic quark model for the light degrees of freedom and in the limit of heavy quark spi…
