A new constraint for the parameters of the K$_{varrho}_{3}$ scalar form factor
In order to determine the slope lambda /sub 0/ of the K/sub l3/ form factor, low-energy theorems of hard-pion current algebra with (3*, 3)+ (3, 3*) symmetry breaking are used. It is found that when lambda /sub 0/ is large and negative, lambda /sub 0/' must become positive, allowing a large fami...
