Event Shapes at the Tevatron

We present a complementary set of ``Indirectly Global Event Shapes'' proposed for study at hadron colliders. These observables are designed to reconcile the seemingly conflicting theoretical requirement of ``globalness'' with the realities of the hadron collider environment--namely, the limited detector coverage in the forward region. Of particular interest is the study of event shape distributions as a means of understanding non-perturbative hadronization effects. Specifically, these are considered within the Dokshitzer-Marchesini-Weber (DMW) analytical model of power corrections. We present a preliminary account of two observables, the central transverse thrust and thrust minor, as measured using the CDF detector at the Tevatron.
