Heavy to light form-factors in the heavy mass to large energy limit of QCD

J. Charles; L. Oliver; J.-C. Raynal; A. Le Yaouanc; O. Pène

We argue that the large energy effective theory (LEET), originally proposed by Dugan and Grinstein, is applicable to exclusive semileptonic, radiative, and rare heavy-to-light transitions in the region where the energy release E is large compared to the strong interaction scale and to the mass of the final hadron, i.e., for

not close to the zero-recoil point. We derive the effective Lagrangian from the QCD one, and show that in the limit of heavy mass M for the initial hadron and large energy E for the final one, the heavy and light quark fields behave as two-component spinors. Neglecting QCD short-distance corrections, this implies that there are only three form factors describing all the pseudoscalar to pseudoscalar or vector weak current matrix elements. We argue that the dependence of these form factors with respect to M and E should be factorizable, the M dependence
