- Searching the needle in a haystack, or rather: is the neutrino a Majorana particle?
GERDA is data taking at the italian Gran Sasso laboratory searching for one of the rarest process in nature: neutrinoless double beta decay. We try to unravel whether particles can be created without being balanced by anti-particles. Such a process is not allowed by the Standard Model of Particle Physics and if observed, would require that the elementary neutrino particle is identical with its anti-particle, or alternatively, point to new interactions that violate lepton number conservation. In this project you would would focus on the data analysis and develop and optimize an analysis strategy to decipher background from signal events.
Concrete, you would study events created by K42/Ar42 beta decays, penetrating the n-plus deadlayer of a high-purity germanium diode and create so called slow-pulses. You would start with a data set from calibration data available. First you would learn to apply the standard cuts to create distributions of these slow-pulse events. Then you would try alternative methods and develop novel algorithms which try to extract the maximum information based on the physics process of the signal and compare the separation capabilities with the standard methods. You could also try to model the signals to get a deeper understanding, which in turn might be useful to devise an optimal analysis strategy. This could include deep learning and neural networks techniques. You should be familiar with or willing to learn C/C++, the linux command line interface, scientific programming, and statistics. The work takes place within an international collaboration and there will be many opportunities to practice presenting your analysis results to other physicists.
