Utilizing recent deep inelastic scattering data and our recent NLO analysis,
we present a QCD analysis of the proton in order to determine the
parton distributions at next-to-next-to-leading order (NNLO) of QCD. We
also study the heavy quark contributions to the proton structure function
2(x;Q2), with i = c, b. Our NNLO analysis will be performed within the
modified minimal subtraction factorization and renormalization scheme.
This analysis is undertake within the framework of the so called ?zero-mass
variable flavor number scheme? (ZM-VFNS) parton model predictions at
high energy colliders where the heavy quarks (c, b, t) considered as massless
partons within the nucleon.
