Abstract

By considering a flavor expansion about the SU(3) flavor symmetric point, we investigate how flavor blindness constrains octet baryon matrix elements after SU(3) is broken by the mass difference between quarks. Similarly to hadron masses we find the expansions to be constrained along a mass trajectory where the singlet quark mass is held constant, which provides invaluable insight into the ...
