New near-threshold mesons
Thomas D. Cohen, Boris A. Gelman, Shmuel Nussinov
We show that under a number of rather plausible assumptions QCD spectrum may contain a number of mesons which have not been predicted or observed. Such states will have the quantum…
Heavy Baryons: A Combined Large N_c and Heavy Quark Expansion for Electroweak Currents
Boris A. Gelman
The combined large N_c and heavy quark limit for baryons containing a single heavy quark is discussed. The combined large N_c and heavy quark expansion of the heavy quark bilinear…
The Nucleon-Nucleon Interaction and Large N_c QCD
Manoj K. Banerjee, Thomas D. Cohen, Boris A. Gelman
The nature of the nonrelativistic nucleon-nucleon potential in the large N_c limit is discussed. In particular, we address the consistency of the meson exchange picture of nucleon…
Model-Independent Predictions for Low Energy Isoscalar Heavy Baryon Observables in the Combined Heavy Quark and Large Expansion
Z. Aziza Baccouche, Chi-Keung Chow, Thomas D. Cohen +1
Model-independent predictions for excitation energies, semileptonic form factors and electromagnetic decay rates of isoscalar heavy baryons and their low energy excited states are…
Excited Heavy Baryons and Their Symmetries III: Phenomenology
Z. Aziza Baccouche, Chi-Keung Chow, Thomas D. Cohen +1
Phenomenological applications of an effective theory of low-lying excited states of charm and bottom isoscalar baryons are discussed at leading and next-to-leading order in the com…
Excited Heavy Baryons and Their Symmetries II: Effective Theory
Chi-Keung Chow, Thomas D. Cohen, Boris A. Gelman
We develop an effective theory for heavy baryons and their excited states. The approach is based on the contracted O(8) symmetry recently shown to emerge from QCD for these states…
