and Amplitudes in Chiral Perturbation Theory
Martin J. Savage, Roxanne P. Springer
We explore the S-wave and P-wave amplitudes for and interactions using chiral perturbation theory to . In contrast to the large corrections found…
Hadronic and Electromagnetic Interactions of Quarkonia
Jiunn-Wei Chen, Martin J. Savage
We examine the hadronic interactions of quarkonia, focusing on the decays psi(2s)->psi pi pi and upsilon(2s)-> upsilon pi pi. The leading gluonic operators in the multipole expansi…
The Weak Interaction
Martin J. Savage, Roxanne P. Springer
We calculate the leading contribution to the weak coupling in heavy baryon chiral perturbation theory, including the SU(3) breaking terms arising at one-loop. This coupling g…
Power Counting in Dimensionally Regularized NRQCD
Michael Luke, Martin J. Savage
We present a scheme for calculating in NRQCD with consistent power counting in the heavy quark velocity v. As an example, we perform the systematic matching of an external current…
Non-1/m_b^n Power Suppressed Contributions to Inclusive b->s l+ l- Decays
Jiunn-Wei Chen, Gautam Rupak, Martin J. Savage
We compute non-perturbative contributions to b->s l+ l- that are not explicitly suppressed by powers of the b-quark mass. They are proportional to lambda_2 and arise from an interf…
Analyticity, Shapes of Semileptonic Form Factors, and B to pi l nu
C. Glenn Boyd, Martin J. Savage
We give a pedagogical discussion of the physics underlying dispersion relation-derived parameterizations of form factors describing B -> pi l nu and B -> D l nu. Moments of the dis…
