Baryon Decay

This is an extension of the prediction of strange baryon decays to the decays of charmed baryons using QCD sum rules. Using QCD sum rules, we estimate the decay [Formula: see text]. Although some weak decays of the [Formula: see text] have been measured, since it is difficult to measure [Formula: see text] our estimates should be useful for future experiments.

Using the factorization approach and considering the contributions of the current–current, QCD penguin and electroweak penguin operators at the leading approximation, the decay amplitudes and decay widths of [Formula: see text] and [Formula: see text] transitions, where q = u, d, s and P and V are pseudoscalar and vector mesons, are calculated in terms of the transition form factors of the Bq→Dq and [Formula: see text]. Having computed those form factors in three-point QCD sum rules, the branching fraction for these decays are also evaluated. A comparison of our results with the predictions of the perturbative QCD as well as the existing experimental data is presented.
