Abstract
We describe a new formalism which aims to unify particle production
in high energy hadronic/nuclear collisions in the Color Glass Condensate formalism
at small $x$ (low $p_t$) with that of collinear factorization of perturbative
QCD at high $p_t$ (large $x$). To do so, in addition to the classical color field
representing small $x$ gluons of a target hadron or nucleus we also include large
$x$ gluons of the target. We then calculate the scattering amplitude for
a projectile quark scattering from both large and small $x$ gluons of the target. This
allows us to generalize the Color Glass Condensate formalism to include high $p_t$
deflection of the quark projectile. We discuss the remaining steps needed to derive
expressions for particle production cross sections in high energy collisions, in both small
and large $x$ (low and high $p_t$) kinematics , including quantum effects which
would contain both large $1/x$ and $Q^2$ logarithms.
