Mai 22, 2019 – Daniela Mockler wins "Prize for best speaker"

Dr. Daniela Mockler

At the BPS meeting in May 2019, Dr. Daniela Mockler, who recently did her doctorate at KSETA, was awarded the "Prize for best speaker". Congratulations!

The young scientist contest has a long tradition at the annual BPS meeting. Both doctoral students and young postdocs with less than 5 years of professional experience after their PhD defense are eligible to take part in the competition. From among the applicants, the committee initially invited eight speakers to a pre-selection and chose three of them as finalists, who presented their papers at the BPS meeting on May 22. The three finalists will also have the opportunity to write an article on their topic for the B-Phy Magazine of the Belgian Physical Society.

March 2019 – Installation of the first antenna for the AugerPrime Radio Upgrade

The radio upgrade, which is part of the AugerPrime upgrade, is a very important part of the future research of the Pierre Auger Observatory by adding array-based composition sensitivity for large zenith angles, for which the scintillator upgrade is not effective. Having good composition-sensitive information up to very large zenith angles is crucial for composition-improved anisotropy studies and adds to the overall aperture of the observatory.

September 2018 – KSETA PhD student Denise Müller receives prize for best presentation

For her presentation at the conference "11th International Workshop on Top Quark Physics 2018", Denise Müller, PhD student at the Institute of Experimental Particle Physics (ETP), was awarded the prize for the best young scientist presentation in front of 130 participants.

The 11th edition of the conference "International Workshop on Top Quark Physics" took place in Bad Neuenahr from 16 to 21 September. This annual conference brings together experts from theory and experiment who deal with the heaviest of the six quarks, the top quark. Traditionally, the Young Scientist Forum gives young scientists the opportunity to show their work in short presentations. Denise Müller reported on the measurement of the single top quark production in the t channel with data from the CMS experiment, where she does research together with other colleagues from ETP under the supervision of Dr. Thorsten Chwalek.

While top quarks are generated in pairs with top antiquarks in strong interaction, the generation of single top quarks takes place in weak interaction, the secrets of which have not yet been revealed in detail. In Denise Müller's analysis it was possible to measure the relationship between the production probabilities of individual top quarks and individual top antiquarks with unprecedented precision and thus to make statements about the inner structure of the proton.

The KIT is involved in the CMS experiment with a ninety-member working group headed by Prof. Thomas Müller. In 2012, the long-sought Higgs particle was also discovered there.

July 2018 – Master students from India visited KSETA

Between May and July 2018 five  Master students from IIT Bombay in Mumbai and another Master student from Sardar Vallabhbhai National Institute Of Technology in Surat visited KSETA with a KHYS Internship Grant.

Their local hosts were the KSETA Doctoral Fellows Jochen Gemmler, Thomas Huber, Aswathi Balagopal, Mridula Prathapan and Alaa Kuotb Awad.

The interns participated in projects related to the current and future experiments Belle in Tsukuba (Japan), milliQan at CERN in Geneva (Switzerland), and IceCube Gen2 and IceTop at the South Pole, as well as the development of CMOS sensor technology.

New findings on cosmic radiation

KIT Young Investigator Group Contributes Significantly to the AMS Experiment on the International Space Station ISS


The latest results of the measurement of high-energy particles with the detector AMS on the International Space Station ISS deepen our understanding of the origin and nature of cosmic radiation.

A junior research group of the Karlsruhe Institute of Technology (KIT) under the leadership of Dr. Iris Gebauer is significantly involved in the experiment: It played a leading role in measuring the total flow of electrons and positrons.

The spokesperson of the AMS project, Professor Samuel C. C. Ting, presented the results at the CERN Research Centre.

Researchers from the Institute of Experimental Particle Physics (ETP) at KIT, led by Professor Wim de Boer, were involved in the development and construction of several components of the AMS detector. In 2011, the KIT set up the Young Investigator Group (YIG) "Cosmic Ray Transport Models for Dark Matter Searches with AMS-02" under the direction of Dr. Iris Gebauer to analyze the data. The YIG has taken the lead in measuring the total flow of electrons - negatively charged elementary particles - and positrons - antiparticles of electrons with opposite charges.

Press Release of KIT

July 2014: CMS closes major chapter of Higgs measurements

The data reveal that the particle discovered at CERN continues to behave just like the Standard Model predicts
Compatibility of Higgs boson couplings to vector bosons (V) and fermions (f) with the standard model expectation (diamond).

Since the discovery of a Higgs boson by the CMS and ATLAS Collaborations in 2012, physicists at the LHC have been making intense efforts to measure this new particle’s properties. The Standard Model Higgs boson is the particle associated with an all-pervading field that is believed to impart mass to fundamental particles via the Brout-Englert-Higgs mechanism. Awaited for decades, the 2012 observation was a historical milestone for the LHC and led to the award of the 2013 Nobel Prize in Physics to Peter Higgs and François Englert. An open question arising from the discovery is whether the new particle is the one of the Standard Model -- or a different one, perhaps just one of many types of Higgs bosons waiting to be found. Since the particle’s discovery, physicists at the LHC have been making intense efforts to answer this question.

This week, at the 37th International Conference on High Energy Physics , a bi-annual major stage for particle physics, which in 2014 is held in Valencia, Spain, the CMS Collaboration is presenting a broad set of results from new studies of the Higgs boson. The new results are based on the full Run 1 data from pp collisions at centre-of-mass energies of 7 and 8 TeV. The analysis includes the final calibration and alignment constants and contains about 25 fb-1 of data.
