| dc.description | Most previous calculations of the annihilation decay rates of heavy quarkonium were based on factorization assumptions that were unproven and, in some cases, even incorrect. The recent development of a general factorization formula for heavy quarkonium annihilation rates has provided a rigorous theoretical foundation for such calculations. The factorization formula is based on the use of the effective field theory NRQCD to factor the decay rate into short-distance coefficients that can be calculated in perturbation theory and long-distance matrix elements that can be computed using lattice simulations. This approach allows annihilation decay rates to be computed entirely from first principles. | |
