Kaon-Nucleon Couplings for Weak Decays of Hypernuclei
M. J. Savage, R. P. Springer
We investigate the weak kaon-nucleon (NNK) S-wave and P-wave interactions using heavy baryon chiral perturbation theory. The leading 1-loop SU(3) breaking contributions to the $ppK…
Hadron Spectra for Semileptonic Heavy Quark Decay
Adam F. Falk, Michael Luke, Martin J. Savage
We calculate the leading perturbative and power corrections to the hadronic invariant mass and energy spectra in semileptonic heavy hadron decays. We apply our results to the s…
Renormalons in Effective Field Theories
Michael Luke, Aneesh V. Manohar, Martin J. Savage
We investigate the high-order behavior of perturbative matching conditions in effective field theories. These series are typically badly divergent, and are not Borel summable due t…
Electromagnetic Moments of the Baryon Decuplet
M. N. Butler, M. J. Savage, R. P. Springer
We compute the leading contributions to the magnetic dipole and electric quadrupole moments of the baryon decuplet in chiral perturbation theory. The measured value for the magneti…
Nonperturbative Contributions to the Inclusive Rare Decays and
Adam F. Falk, Michael Luke, Martin J. Savage
We discuss nonperturbative contributions to the inclusive rare decays and . We employ an operator product expansion and the heavy quark effect…
Heavy Quark Fragmentation to Baryons Containing Two Heavy Quarks
Adam F. Falk, Michael Luke, Martin J. Savage +1
We discuss the fragmentation of a heavy quark to a baryon containing two heavy quarks of mass . In this limit the heavy quarks first combine perturbatively into…
