We have reanalyzed reaction cross sections of ~(16)N on a ~(12)C target.The nucleon density distribution of ~(16)N,especially surface density distribution,was e
Based on the nonrelativistic QCD factorization approach, O(αsv2) corrections to J/ψ plus ηc production in e+e-annihilation at √ s=10.6 GeV are calculated in
