DIRC for a Higher Luminosity B Factory

The DIRC, a novel type of Cherenkov ring imaging device, is the primary hadronic particle identification system for the BaBar detector at the asymmetric B-factory Pep-II at SLAC. It is based on total internal reflection and uses long, rectangular bars made from synthetic fused silica as Cherenkov radiators and light guides. BaBar began taking data with colliding beams in late spring 1999. This paper describes the challenges for the DIRC in a higher luminosity environment and shows solutions to these challenges.

ep Physics at High Q-squared

This article summarizes a talk presented at the SLAC Summer Institute 2000, SLAC, Stanford, USA. The HERA ep collider allows the measurement of the proton structure and tests of the Standard Model in a large region of phase space that has not been accessible before. Such tests provide the framework for the H1 and ZEUS Collaborations to look for physics beyond the Standard Model.

The strong coupling and the gluon density from jets in DIS

The extraction of the parameters of perturbative QCD is one of the main tasks for the HERA experiments. Studies on the structure of the hadronic final states with jet algorithms give a direct handle on the parton density functions and the strong coupling strength over a wide kinematic range. In this article, new results of the H1 and ZEUS collaborations for the strong coupling and the gluon density in the proton are presented.

Inclusive Hadron Production and Dijets at HERA

This article summarizes a talk given at the International Symposium on Multiparticle Dynamics 1999 in Providence/USA. It provides an overview on the variety of measurements of the hadronic final state in jet production for deep-inelastic scattering and photoproduction at HERA.

Issues on NLO pQCD Programs

This paper summarizes a talk presented at the Durham HERA '98 Workshop. We compare the features that are available in NLO pQCD programs and demonstrate that understanding where in phase space NLO calculations are accurate is vital for extracting information from measurements at the HERA experiments.
