  An accurate quantum three-body calculation is performed for the new type of
big-bang nucleosynthesis (BBN) reactions that are catalyzed by a long-lived
negatively-charged, massive leptonic particle (called X^-) such as the
supersymmetric (SUSY) particle stau. The reactions studied here includes, i)
4He-transfer reactions such as (4He X)+d --> 6Li+X, ii) radiative capture
reactions such as (7Be X)+ p --> (8B X) + gamma, iii) three-body breakup
reactions such as (7Li X)+ p --> 4He+4He+X, iv) charge-exchange reactions such
as (p X)+4He -->(4He X) +p, and v) neutron induced reactions such as (8Be X)+ n
-->9Be+X, where (A X) denotes a Coulombic bound state of a nucleus A and X^-.
In recent papers it has been claimed that some of the catalyzed BBN reactions
have significantly large cross sections so as to markedly change the abundances
of some elements, not only giving a solution to the 6Li-7Li problem (calculated
underproduction of 6Li by a factor of 1000 and overproduction of 7Li+7Be by a
factor of nearly 3) but also imposing strong restrictions on the lifetime and
the primordial abundance of X^-. However, most of the calculations of these
reaction cross sections in the literature were performed assuming too naive
models or approximations that are unsuitable for the complicated low-energy
nuclear reactions. We use a high-accuracy few-body calculational method
developed by the authors, and provide precise cross sections and rates of these
catalyzed BBN reactions for use in the BBN network calculation.
