New DFG Research Group: “What Does a Neutrino Weigh?”

14.04.2015

German Research Foundation provides approximately two million euros in funding

A new research group, established at Heidelberg University with funding from the German Research Foundation (DFG), is working on determining the mass of the elementary particle neutrino.

The research, which began in April 2015, will receive funds of nearly two million euros over a three-year period. Beside physicists of Ruperto Carola researchers from the Max Planck Institute for Nuclear Physics in Heidelberg and the Universities of Mainz and Tübingen are part of the project.

Prof. Dr. Christian Enss of the Kirchhoff Institute for Physics at Heidelberg University is the spokesperson for the “Neutrino Mass Determination by Electron Capture in Holmium-163“ (ECHo) DFG research group.

“For a long time the neutral elementary particle neutrino was thought to be massless, which turned out to be wrong. Since then, particle physicists all over the world have been pursuing the fundamental task of determining the neutrino’s tiny mass,” says Prof. Enss.

To get closer to answering the question of the neutrino’s weight, the new DFG research group intends to develop and deploy a special detector technology known as the magnetic microcalorimeter.

These detectors will be used in experiments to measure the decay spectrum of the radioactive element holmium-163 with extreme precision. As Prof. Enss explains, holmium-163 decays into dysprosium-163 when an electron from the holmium shell is “captured” by the nucleus. A neutrino is released at the same time.

The missing energy at the end point of the decay spectrum should point to the mass of the neutrino. “We want to develop this approach over the long term to make it the most sensitive method of directly determining the mass of neutrinos,” says the Heidelberg physicist.

The researchers are also hoping to gain some new basic knowledge of elementary particles in general. “This new detector technology also holds a great deal of potential for further experiments in particle physics and related fields,” underscores Prof. Enss. Approximately 1.4 million euros of the total DFG funding is earmarked for Heidelberg arm of the ECHo DFG research group.

Im Focus: Better thermal conductivity by adjusting the arrangement of atoms

Adjusting the thermal conductivity of materials is one of the challenges nanoscience is currently facing. Together with colleagues from the Netherlands and Spain, researchers from the University of Basel have shown that the atomic vibrations that determine heat generation in nanowires can be controlled through the arrangement of atoms alone. The scientists will publish the results shortly in the journal Nano Letters.

In the electronics and computer industry, components are becoming ever smaller and more powerful. However, there are problems with the heat generation. It is...

Im Focus: First-ever visualizations of electrical gating effects on electronic structure

Scientists have visualised the electronic structure in a microelectronic device for the first time, opening up opportunities for finely-tuned high performance electronic devices.

Physicists from the University of Warwick and the University of Washington have developed a technique to measure the energy and momentum of electrons in...

Im Focus: Megakaryocytes act as „bouncers“ restraining cell migration in the bone marrow

Scientists at the University Würzburg and University Hospital of Würzburg found that megakaryocytes act as “bouncers” and thus modulate bone marrow niche properties and cell migration dynamics. The study was published in July in the Journal “Haematologica”.

Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow. The bone marrow produces all types of blood cells: red...

Im Focus: Artificial neural network resolves puzzles from condensed matter physics: Which is the perfect quantum theory?

For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.

Is that a dog or a cat? Such a classification is a prime example of machine learning: artificial neural networks can be trained to analyze images by looking...

Im Focus: Extremely hard yet metallically conductive: Bayreuth researchers develop novel material with high-tech prospects

An international research group led by scientists from the University of Bayreuth has produced a previously unknown material: Rhenium nitride pernitride. Thanks to combining properties that were previously considered incompatible, it looks set to become highly attractive for technological applications. Indeed, it is a super-hard metallic conductor that can withstand extremely high pressures like a diamond. A process now developed in Bayreuth opens up the possibility of producing rhenium nitride pernitride and other technologically interesting materials in sufficiently large quantity for their properties characterisation. The new findings are presented in "Nature Communications".

The possibility of finding a compound that was metallically conductive, super-hard, and ultra-incompressible was long considered unlikely in science. It was...
