The particle physicist Dr. Matthias Schott will establish a junior research group at Johannes Gutenberg University Mainz (JGU) that will make high precision measurements of the W boson particle, one of the fundamental building blocks of matter.
This new research group will be receiving financial support from the German Research Foundation (DFG) over the coming years. The team is part of the Experimental Particle and Astroparticle Physics (ETAP) work group at JGU and thus actively involved in the university's Cluster of Excellence Precision Physics, Fundamental Interaction and Structure of Matter (PRISMA).Its investigations will be conducted using data taken by the ATLAS Experiment at CERN's Large Hadron Collider (LHC) in Geneva. "The precision measurements will help us to better understand the structure of matter," is how Matthias Schott explains his expectations. The project has particular significance in view of the recently announced discovery of the Higgs boson at CERN.
W bosons are electrically charged elementary particles that mediate the weak interaction, which is for example responsible for the decay of the neutron. As their mass is roughly 80 times that of a proton, W bosons are relatively heavy. Although they can be generated in particle accelerators like the LHC, they decay very rapidly. The goal of the new junior research group is to conduct the precision measurement of the mass of the W boson with a target precision of 0.01%, implementing several innovative approaches on data-analyses and large-scale computing. This is one of the most difficult tasks in modern particle physics due to the large number of experimental and theoretical aspects that need to be taken into account.
"We are looking forward to our collaboration with Dr. Martin Schott, whose research project perfectly complements our current work in particle physics," explains Professor Dr. Volker Büscher of the Experimental Particle and Astroparticle Physics (ETAP) group at Mainz University. Approximately 50 physicists from JGU are participating in research at CERN, in particular in the ATLAS experiment, one of two major experiments tasked with searching for the Higgs particle and providing definitive proof of its existence.
It is the intention of the German Research Foundation to use its Emmy Noether Program as a means of helping young scientists attain independence when it comes to research by enabling them to head up junior research groups and thus gain the qualifications needed to teach at university. Over recent years, Matthias Schott has been working as a researcher at CERN on a project involving the generation of low energy gauge bosons using the LHC. He will start forming the work group in the fall of 2012 in Mainz.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
