Nonanalytic m 1/2 q and m q ln m q chiral corrections to the baryon magnetic moments are computed. The calculation includes contributions from both intermediate octet and decuplet baryon states. Unlike the one-loop contributions to the baryon axial currents and masses, the contribution from decuplet intermediate states does not partially cancel that from… (More)

The decay constants for the D and D S mesons, denoted f D and f D S respectively, are equal in the SU (3) V limit, as are the hadronic amplitudes for B S −B S and B 0 −B 0 mixing. The leading SU (3) V violating contribution to (f D S /f D) and to the ratio of hadronic matrix elements relevant for B S − B S and B 0 − B 0 mixing amplitudes are calculated in… (More)

The possibility of interpreting baryons containing a single heavy quark as bound states of solitons (that arise in the nonlinear sigma model) and heavy mesons is explored. Particular attention is paid to the parity of the bound states and to the role of heavy quark symmetry.

These lectures introduce some of the basic ideas of effective field theories. The topics discussed include: relevant and irrelevant operators and scaling, renormal-ization in effective field theories, decoupling of heavy particles, power counting, and naive dimensional analysis. Effective Lagrangians are used to study the ∆S = 2 weak interactions and chiral… (More)

Since fields in the heavy quark effective theory are described by both a velocity and a residual momentum, there is redundancy in the theory: small shifts in velocity may be absorbed into a redefinition of the residual momentum. We demonstrate that this trivial reparameterisation invariance has non-trivial consequences: it relates coefficients of terms of… (More)

These lectures introduce some of the basic ideas of eective eld theories. The topics discussed include: relevant and irrelevant operators and scaling, renormal-ization in eective eld theories, decoupling of heavy particles, power counting, and naive dimensional analysis. Eective Lagrangians are used to study the S = 2 w eak interactions and chiral… (More)

The interaction of quarkonium with nuclei is studied in the m Q → ∞ limit of QCD, where the binding energy is found to be exactly computable. The dominant contribution to the interaction is from two-gluon operators. The forward matrix elements of these two-gluon operators can be determined from the QCD scale anomaly, and from deep inelastic scattering. We… (More)

We discuss the matching conditions and renormalization group evolution of non-relativistic QCD. A variant of the conventional MS scheme is proposed in which a subtraction velocity ν is used rather than a subtraction scale µ. We derive a novel renormalization group equation in velocity space which can be used to sum logarithms of v in the effective theory.… (More)

The differential decay spectrum dΓ/dE e dq 2 for the semileptonic decay of an unpolar-ized hadron containing a b-quark, and the decay spectrum dΓ/dE e dq 2 dcos θ for polarized Λ b decay are computed to second order in the 1/m b expansion. Most of the 1/m 2 b corrections have a simple physical interpretation, which is discussed in detail. The implications… (More)

We study the low-energy dynamics of all N = 1 supersymmetric gauge theories whose basic gauge invariant fields are unconstrained. This set includes all theories whose matter Dynkin index is less than the index of the adjoint representation. We study the dynamically generated superpotential in these theories, and show that there is a W = 0 branch if and only… (More)
