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.
