Patterns of Spontaneous Chiral Symmetry Breaking in the Large-Nc Limit of QCD-Like Theories
M. Knecht, E. de Rafael
It is shown that in vector-like gauge theories, such as QCD, and in the limit of a large number of colours Nc, the ordering pattern of narrow vector and axial-vector states at low…
How Small Can the Light Quark Masses Be?
Laurent Lellouch
We derive rigorous lower bounds for the combinations of light quark masses (m_s+m_u) and (m_d+m_u).
Light Quark Masses in QCD
Eduardo de Rafael
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 r…
How small can the light quark masses be?
L. Lellouch, E. de Rafael, J. Taron
We derive lower bounds for the combination of light quark masses m_s +m_u and m_d +m_u. The derivation is based on first principles: the analyticity properties of two-point functio…
Low-Energy QCD and Ultraviolet Renormalons
S. Peris, E. de Rafael
We discuss the contribution of ultraviolet (UV) renormalons in QCD to two-point functions of quark current operators. This explicitly includes effects due to the exchange of one re…
