Henrik Jabusch, who is originally from Elmshorn, Schleswig-Holstein, moved to Hamburg a few years ago. In 2019, he graduated from his Master at Universität Hamburg, with a thesis on “Constraints of Leptoquark Models with CMS Data.” Back then, he was part of Prof. Dr. Johannes Haller’s group and, after graduating, continued as a PhD student in the same group.

What is the topic of your research?

Johannes Haller’s research group is part of the Compact Muon Solenoid (CMS) collaboration, meaning, we collect data within the CMS experiment located at the Large Hadron Collider at CERN. We then analyze those data to either perform measurements of Standard Model properties or search for physics beyond the Standard Model (BSM).
My PhD project is actually related to Ksenia de Leo’s project.  While her research is focusing on possible new heavy resonances decaying into pairs of top quarks, I am investigating non-resonant BSM models which cause modifications of the invariant mass distribution of the top quark pair. Prominent examples for theories predicting such signatures often include new particles and/or new couplings, such as axion-like particles and Standard Model effective field theory.

What fascinates you about your research focus?

I’m fascinated by the fact that we do basic research trying to unravel the mysteries of new physics. We know that the Standard Model has its shortcomings, so there must be something beyond. And because we didn’t find anything yet, we constantly need to improve our research by using better techniques, studying new models and producing more data.

What do you like about the cluster Quantum Universe?  

I like that Quantum Universe gives young researchers like me the opportunity to do science and talk about it. Furthermore, it’s interesting and inspiring to see what people in other research areas of the cluster work on and how they progress. I’m also a big fan of the cluster’s lecture series, where the hot topics of physics are presented in three sessions by an absolute expert in that field. The next lecture series is about to start in November, so I’m really looking forward to that!

What do you like to do in your free-time?

In my free time, I enjoy doing sports. To be exact, I have been playing soccer for many years, but I also like trying new things. This year for example, my friends and I discovered spikeball, which is a two-versus-two net game inspired by concepts from volleyball. Great fun!
I also enjoy cooking, and I would like to travel more as it’s now becoming little by little possible again.
