QCD Sum Rule Analysis of the Subleading Isgur-Wise Form Factor
M. Neubert, Z. Ligeti, Y. Nir
We present a QCD sum rule calculation of the spin-symmetry violating universal function , which appears at order in the heavy quark expansion of meson form…
Second Order Power Corrections in the Heavy Quark Effective Theory II. Baryon Form Factors
Adam F. Falk, Matthias Neubert
The analysis of corrections of the previous paper is extended to the semileptonic decays of heavy baryons. We focus on the simplest case, the ground state baryons,…
Second Order Power Corrections in the Heavy Quark Effective Theory I. Formalism and Meson Form Factors
Adam F. Falk, Matthias Neubert
In the heavy quark effective theory, hadronic matrix elements of currents between two hadrons containing a heavy quark are expanded in inverse powers of the heavy quark masses, wit…
Recent Developments in the Theory of Heavy-Quark Decays
Matthias Neubert
I report on recent developments in the heavy-quark effective theory and its application to meson decays. The parameters of the effective theory, the spin-flavor symmetry limit,…
The Residual Mass Term in the Heavy Quark Effective Theory
Adam F. Falk, Matthias Neubert, Michael Luke
We reformulate the heavy quark effective theory in the presence of a residual mass term, which has been taken to vanish in previous analyses. While such a convention is permitted,…
