But that was only true for massless quarks!

• CC is suppressed due to final state c-quark Need to know s-quark sea and mc

• Modeled with "slow-rescaling"

• Measured by NuTeV/CCFR using dimuon events (nN ® m cX ® mmX)

• (M. Goncharov et al., Phys. Rev. D64: 112006,2001 and A.O. Bazarko et al., Z.Phys.C65:189-198,1995)
