PhD position (m/f/x): Data analysis for exotic hadrons at hadronic thresholds
The work of the chair of experimental physics 1 focuses on basic research: One of the most essential elements of todays education and research is to gain a better understanding of the structure of matter and the fundamental principles of nature. In this process the basic research of physics plays an important role as it provides a base for technical innovations and development. Hadron Physics deals with strong interacting particles consisting of quarks and gluons. Among those hadrons also rank the building blocks of the atomic nucleus, the proton and the neutron. There are many other hadrons that can only be created via collisions of high energetic particles in big particle accelerators. The created hadrons are detected by modern and complex detectors to examine their composition and interactions.
The position is embedded in two research programs. DEMOS ("Democratizing Models") is an ErUM research initiative developing a federated, interoperable standard for describing, sharing and re-evaluating physics models across particle, hadron, nuclear, neutrino and astroparticle physics. Hadronic coupled-channel amplitudes are one of its flagship applications: they are analytically intricate and rarely reproducible from the publication alone, which makes them an ideal test case for the new standard. HADRON 2030 is an intercollaborative research network dedicated to studies of hadron physics. Within the ExHAT (Exploration of Heavy Hadrons at Thresholds) project, we will explore heavy hadrons at thresholds using spectroscopy methods with LHCb data and inclusive production studies with ALICE. The flagship case is the doubly charmed tetraquark Tcc(3875)+, which lies a fraction of an MeV below the D0 D*+ threshold. Line shape, pole position, three-body DD-pi dynamics and isospin breaking have to be disentangled in a joint effort of theory and experiment.
Scope: part-time
Duration: fixed-term, 3 years

The Ruhr-Universität Bochum is one of Germany’s leading research universities, addressing the whole range of academic disciplines. A highly dynamic setting enables researchers and students to work across the traditional boundaries of academic subjects and faculties. To create knowledge networks within and beyond the university is Ruhr-Universität Bochum’s declared aim.
The Ruhr-Universität Bochum stands for diversity and equal opportunities. For this reason, we favour a working environment composed of heterogeneous teams, and seek to promote the careers of individuals who are underrepresented in our respective professional areas. The Ruhr-Universität Bochum expressly requests job applications from women. In areas in which they are underrepresented they will be given preference in the case of equivalent qualifications with male candidates. Applications from individuals with disabilities are most welcome.
