Light Quark Masses in QCD
arXiv:hep-ph/9709430 · doi:10.1016/S0920-5632(97)01071-2
Abstract
Invited talk given at the conference QCD97, Montpellier, France. I report on rec ent work done in collaboration with Laurent Lellouch and Josep Taron concerning the derivation of rigorous lower bounds for the combination of light quark massese s m_s + m_u and m_d + m_u.
