Analytic Properties of Form Factors in Strictly Confining Models

摘要

An argument is presented showing that strict confinement implies the possible existence of an (unwanted) branch point at q exp 2 =0 in the form factors. In case of a bag extended to infinity in the relative time, the branch point is certainly there (provided that the form factor is non zero at q exp 2 =0). (Atomindex citation 11:526687)
