What can a relativistic quark model tell us about charmed mesons?
M. Sutherland, B. Holdom, S. Jaimungal +1
A relativistic quark model is extended to incorporate chiral and gauge symmetries. We obtain the DD*pi and DD*gamma couplings and find that the ratio Gamma(D*0->D0pi0)/Gamma(D*0->D…
Anomalous Thresholds and the Isgur-Wise Function
B. Holdom, M. Sutherland
The original de Rafael-Taron bound on the slope of the Isgur-Wise function at zero recoil is known to be violated in QCD by singularities appearing in an unphysical region. To be c…
1/m_c Expansion of Omega_b -> Omega_c^(*) Semileptonic Decay Form Factors
M. Sutherland
A simple model of Omega_Q and Omega_Q^(*) baryons containing one heavy quark Q is constructed. Amplitudes are represented by loop graphs with one line for the heavy quark and anoth…
Comparison of 1/mQ^2 Corrections in Mesons and Baryons
B. Holdom, M. Sutherland, J. Mureika
We extend our relativistic quark model to the study of the decay Lambda_b -> Lambda_c ell nu and verify that the model satisfies the heavy-quark symmetry constraints at order 1/mQ^…
Simply Modeling B -> K* gamma
B. Holdom, M. Sutherland
A simple relativistic model of heavy-light mesons is applied to the rare decay B -> K* gamma in the standard model. We find Gamma(B -> K* gamma)/Gamma(b -> s gamma)=(17 \pm 4)% and…
Linear and higher order power corrections in semileptonic B decays
B. Holdom, M. Sutherland
In previous work we have developed a relativistic quark model of mesons which is consistent with all QCD constraints at zeroth and first order in the heavy quark expansion. Here we…
