The performance of jet finding using only charged tracks in CMS has been investigated. Different jet algorithms have been applied to QCD di-jet events, to hadronic tt multi-jet events and on Z+jets events. Results using jets made with tracks only or calorimeter towers are compared for energy response, angular resolution and jet matching to the leading partons. The jet reconstruction performance...

First we summarize some properties of the nonholonomic r-jets from the functorial point of view. In particular, we describe the basic properties of our original concept of nonholonomic r-jet category. Then we deduce certain properties of the Weil algebras associated with nonholonomic r-jets. Next we describe an algorithm for finding the nonholonomic r-jet categories. Finally we classify all spe...

A remarkable phenomenon in turbulent flows is the spontaneous emergence of coherent large spatial scale zonal jets. In this work a comprehensive theory for the interaction of jets with turbulence, stochastic structural stability theory, is applied to the problem of understanding the formation and maintenance of the zonal jets that are crucial for enhancing plasma confinement in fusion devices. ...

The specific scientific objectives of this project are focused on studying the dynamical coupling between meandering baroclinic jets with the deep flow over steep topography. Emphasis is placed on the initialization of baroclinic jets in numerical models and improving our understanding of the life cycle of energetic flow perturbations excited by meandering of baroclinic jets. The gained knowled...

The idea of a unified model for all astrophysical jets has been considered for quite some time. We present here a few scaling laws relevant to all type of astrophysical jets, analogous to those of Sams et al. (1996) which are widely used for astrophysical black holes. We use Buckingham's Π theorem of dimensional analysis to obtain a family of dimensional relations among the physical quantities ...
