Tracking detectors are of vital importance for collider-based high energy physics (HEP) experiments. The primary purpose of tracking detectors is the precise reconstruction of charged particle ...trajectories and the reconstruction of secondary vertices. The performance requirements from the community posed by the future collider experiments require an evolution of tracking systems, necessitating the development of new techniques, materials and technologies in order to fully exploit their physics potential. In this article we summarize the discussions and conclusions of the 2022 Snowmass Instrumentation Frontier subgroup on Solid State and Tracking Detectors (Snowmass IF03).
Recent dijet results from CDF are presented. The preliminary dijet mass distribution measured by CDF is presented and compared to QCD calculations. Measurements of dijet angular distributions are ...used to place limits on quark compositness. A preliminary measurement of the inclusive dijet differential cross section is presented.
We present a summary of the hadronic final states parallel sessions of the DIS99 workshop. Topics were presented over two days and included both theoretical and experimental talks. Recent progress in ...the understanding of QCD in deep inelastic scattering,

Nucl.Phys.Proc.Suppl.79:740-754,1999 We present a summary of the Hadronic Final States parallel sessions of the
DIS99 Workshop. Topics were presented over two days and included both
theoretical and ...experimental talks. Recent progress in the understanding of QCD
in deep inelastic scattering, e^+e^- collisions, and in gamma and p collisions
was discussed.
The Consumer-Server/Logger (CSL) is the final component in the CDF Data Acquisition chain before data are archived to tape. The CSL buffers data in separate data streams, records file meta ...information into a database and sends a fraction of events to online processors for real time monitoring of data quality. Recently, the CSL was upgraded in order to increase the logging capacity to 80 MB/s. The upgrade consists of commodity servers running Linux. A "Receiver node" distributes data via Gigabit Ethernet to eight parallel "Logger nodes" connected to external disk arrays via a Fibre Channel network. A redundant design and the availability of inexpensive large capacity disk arrays provides a highly available system that is scalable and easy to maintain. We present a description of the CSL upgrade and discuss the experience gained through commissioning to operations.

The experiments at Run 2 of the Tevatron have each accumulated over 1 inverse
femtobarn of high-transverse momentum data. Such a dataset allows for the first
precision (i.e. comparisons between ...theory and experiment at the few percent
level) tests of QCD at a hadron collider. While the Large Hadron Collider has
been designed as a discovery machine, basic QCD analyses will still need to be
performed to understand the working environment. The Tevatron-for-LHC workshop
was conceived as a communication link to pass on the expertise of the Tevatron
and to test new analysis ideas coming from the LHC community. The TeV4LHC QCD
Working Group focussed on important aspects of QCD at hadron colliders: jet
definitions, extraction and use of Parton Distribution Functions, the
underlying event, Monte Carlo tunes, and diffractive physics. This report
summarizes some of the results achieved during this workshop.
