Heavy quark production at HERA and its relevance for the LHC

The import of HERA data on heavy quark production for LHC experiments is discussed. Knowlegde of all aspects of the beauty and charm production process, viz. the parton density functions of colliding hadrons, the hard scatter, and the fragmentation of the quarks into hadrons, can aid LHC experimentation. This short write-up concentrates on possible influences HERA data can have and on the current status (and history) of beauty production from both HERA and Tevatron experiments. In general, next-to-leading order QCD gives a reasonable description of beauty production although some regions of phase space such as low p_T show indications of differences.Comment: 4 pages, to appear in DIS2006 conference proceeding

Inclusive dijet photoproduction and the resolved photon at THERA

A future $ep$ facility, THERA, where electrons of 250 GeV and protons of 920 GeV are collided could provide valuable information on the structure of the photon. With an increase in the centre-of-mass energy of a factor of 3 and an extension of the minimum photon energy fraction carried by the interacting parton of a factor of 10 compared to HERA, a new kinematic regime in the study of the photon will be opened. Inclusive dijet production has been studied and the potential gains the new collider would bring are discussed. The differences between current parametrisations of the photon structure in this new kinematic region are shown to be up to 50%. Comparisons of THERA's capabilities are made with what HERA can currently produce and how it complements $e^+e^-$ colliders addressed.Comment: 10 pages, 6 figures (corrected references).

Data Acquisition in the EUDET Project

The goal of the EUDET project is the development and construction of infrastructure to permit detector R&D for the International Linear Collider (ILC) with larger scale prototypes. It encompasses major detector components: the vertex detector, the tracker and the calorimeters. We describe here the status and plans of the project with emphasis on issues related to data acquisition for future test beam experiments.Comment: 4 pages, 2 figures, to appear in the proceedings of Linear Collider Workshop (LCWS06), Bangalore, Indi

Compilation of detection sensitivities in thermal-neutron activation

Detection sensitivities of the chemical elements following thermal-neutron activation have been compiled from the available experimental cross sections and nuclear properties and presented in a concise and usable form. The report also includes the equations and nuclear parameters used in the calculations
