In high-energy physics, there is a need to investigate alternative silicon sensor concepts that offer cost-efficient, large-area coverage. Sensors based on CMOS imaging technology present such a silicon sensor concept for tracking detectors. [...]

Research and development laboratory measurements of non-irradiated and irradiated planar n+ -in-n pixel sensor structures are systematically investigated to determine the power dissipation of those sensors. Measurements were taken at different operation temperatures, sensor bias voltages, bulk thicknesses, sensor areas, and irradiation fluences. [...]

In order to meet the requirements of the High Luminosity LHC (HL-LHC), it will be necessary to replace the current tracker of the ATLAS experiment. Therefore, a new all-silicon tracking detector is being developed, the so-called Inner Tracker (ITk). [...]

p-values for Model Evaluation
/ Beaujean, Frederik (Munich, Max Planck Inst.) ; Caldwell, Allen (Munich, Max Planck Inst.) ; Kollár, D (CERN) ; Kröninger, K (Gottingen U., II. Phys. Inst.)
A quantitative procedure to decide whether a model provides a good descriptionof data is often based on a specific test statistic and a p-value summarizingboth the data and the statistic's sampling distribution. We provide a Bayesianmotivation for using p-values in the goodness-of-fit problem with no explicitalternative models considered. [...]
