Heavy quark mass expansion of vector and tensor currents and intrinsic charm in nucleon form factors (1505.06942v1)
Published 26 May 2015 in hep-ph and hep-ex
Abstract: The framework of the expansion by subgraphs is used to compute asymptotic expansions for the vector and the tensor currents in the limit of large quark masses. We use the results to obtain an estimate for the influence of heavy quarks on the nucleon electromagnetic and tensor form factors.
