Abstract

Observations tell us that dark matter makes up a large fraction of the material within galaxies. In this COMPUTE seminar Ruth Pöttgen will describe how her research is about forming a better understanding of this material. Her main research activity at the moment is to develop, in an international collaboration, a new experiment called LDMX — the Light Dark Matter eXperiment.
Pöttgen’s main focus within the LDMX collaboration are simulation studies of different detector performance aspects, background rejection capabilities and the sensitivity to dark matter signals. In this, Ruth Pöttgen and collaborators also explore the potential benefit of using different machine learning techniques, especially for cases where more than one electron hit the target at the same time. Moreover, they are starting to think ahead and develop data-driven methods to reduce their reliance on simulations and be ready when LDMX starts taking data in a few years.
