New Emmy Noether Junior Research Group examines role played by W bosons in the structure of matter

31.08.2012
Matthias Schott is to form an independent work group at Mainz University to precisely measure the mass of the W boson

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.

The Standard Model has been the most successful theory in the history of particle physics, describing the fundamental constituents of matter and their interactions. Despite its huge success in the past decades, several crucial questions remain open. Particle physicists still intensely seek to understand how fundamental particles acquire their mass, or in other words, what is the role of the Higgs mechanism in the electroweak symmetry breaking. "The precise mass determination of the three fundamental particles – the W boson, the top quark, and the Higgs boson discovered at the beginning of June 2012 – can provide us with a definite answer," claims Schott.

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.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
