Scalar Form Factors in SU(3) Chiral Perturbation
Submitted to The Journal of High Energy Physics
The scalar form factors for the pions and kaons are
calculated in SU(3) Chiral Perturbation Theory at order
p6, in the isospin limit mu
=md=m^. We find in general sizable
corrections of O(p6). We use our results to
obtain results on the 1/Nc suppressed low energy
constants L4r and
L6r as well as on two
O(p6) low energy constants. We present some
numerical results for masses and decay constants as well.
We derive a relation for the scalar form factors analogous
to Sirlin's relation for vector form factors.
