Spin symmetry in e+e- annihilation into heavy mesons
Description
We employ the spin symmetry of the heavy quark effective theory to discuss the exclusive total cross sections for the production of heavy mesons in electron-positron annihilation. We verify and extend the results derived previously on the basis of spin counting arguments by De Rujula, Georgi and Glashow. (orig.)
