Two loop QCD corrections to e+e−→J/ψ+ηc in asymptotic expansion
Within the framework of NRQCD, the two-loop QCD corrections to the short-distance coefficient for the process e+e−→J/ψ+ηc have been obtained in asymptotic expansion over r=16mc2/s up to r15, sufficient for phenomenological studies. The obtained leading logarithmic terms can facilitate the resummatio...
