摘要：
We present a new technique to calculate loop diagrams in a static and spherical cavity. This numerical method is based on dimensional regularization, adapted to the case of cavity field theories. It is more powerful than any of the existing formalisms. As an example we calculate the self-energies of the low-lying cavity modes of massless quarks to order αs. © 1990.
