Spin-Flavor Structure of Large N Baryons
Roger Dashen, Elizabeth Jenkins, Aneesh V. Manohar
The spin-flavor structure of large N baryons is described in the 1/N expansion of QCD using quark operators. The complete set of quark operator identities is obtained, and used to…
Semiclassical Meson-Baryon Dynamics from Large-Nc QCD
Aneesh V. Manohar
The large- limit of the meson-baryon effective Lagrangian is shown to reduce to a semiclassical field theory. A chiral bag structure emerges naturally in the $N_c\rightarrow \…
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…
Power Suppressed Corrections to Hadronic Event Shape Variables
Aneesh V. Manohar, Mark B. Wise
For high energy processes () there are infrared safe hadronic shape variables that have a calculable perturbative expansion in . However, nonperturbative po…
Baryons in the Large N Limit
Aneesh V. Manohar
The properties of baryons can be computed in a systematic expansion in , where is the number of colors. Recent results on the axial couplings and masses of baryons (fo…
Baryon Magnetic Moments in the 1/N Expansion
Elizabeth Jenkins, Aneesh V. Manohar
Relations among the baryon magnetic and transition magnetic moments are derived in the expansion. Relations which hold to ALL ORDERS in breaking and to leading and…
QCD Corrections and the Endpoint of the Lepton Spectrum in Semileptonic B Decays
Adam F. Falk, Elizabeth Jenkins, Aneesh V. Manohar +1
Recently, Neubert has suggested that a certain class of nonperturbative corrections dominates the shape of the electron spectrum in the endpoint region of semileptonic decay. P…
