Electromagnetic Mass Splittings in Heavy Mesons

Abstract

The electromagnetic contribution to the isomultiplet mass splittings of heavy mesons is reanalyzed within the framework of the heavy mass expansion. It is shown that the leading term in the expansion is given to a good approximation by the elastic term. $1/m_Q$-corrections can only be estimated, the main source of uncertainty now being inelastic contributions. The $1/m_Q$-corrections to the elastic term turn out to be relatively small in both D and B pseudoscalar mesons.
