Arbeitsgruppe Fuchs

In meiner Arbeitsgruppe geht es um Erweiterungen des Standardmodells der Teilchenphysik und deren Phänomenologie am Large Hadron Collider (LHC), zukünftigen Beschleunigern und an der Schnittstelle zur Atomphysik.

Wir gehen den Eigenschaften des Higgs Bosons, Kandidaten für Dunkle Materie und der Baryonasymmetrie des Universums auf den Grund. Dafür entwickeln wir innovative Methoden um Theorievorhersagen im Vergleich zu experimentellen Daten zu testen und um neue sensitive Messungen vorzuschlagen.

In my group, we work on extensions of the Standard Model of particle physics and their phenomenology at the Large Hadron Collider (LHC), future colliders and at the interface to atomic physics.

We investigate the properties of the Higgs boson, candidated for Dark Matter and the baryon asymmetry of the Universe. To do so, we develop innovative methods to confront theory predictions with experimental data and to suggest new sensitive measurements.

As part of the Excellence Cluster QuantumFrontiers, we have close connections to experimental and theoretical atomic physics groups at LUH and PTB, and furthermore to the German and international high-energy community. More information about the junior professorship can be found in this QuantumFrontiers announcement.

TEAM AND POSITIONS

Motivated and talented students, PhD students and postdocs are very welcome to join me and my new group in the quest for particles and phenomena beyond the Standard Model. Please do not hesitate to contact me if you are interested in a Bachelor, Master, PhD thesis, a postdoc or a research visit in my group.

My junior professorship started in June 2021 and I am now building a dynamic research team. Until September 2022, I will be based at CERN, and my team members can also spend a research stay or several shorter visits there before the group will move to Hannover/Braunschweig in the fall 2022.

  • Two PhD positions (85% E13 TVöD) in BSM phenomenology will be available as doctoral students at LUH in collaboration with the Physikalisch-Technische Bundesanstalt/ National Metrology Institute (PTB) Braunschweig. Please apply by 25/11/2021 at PTB (in English or German). One position will focus more on high-energy physics, the other one more on the interface of particle and atomic physics. Please indicate which direction interests you most. Backgrounds in atomic physics, collider physics, cosmology, either from the theoretical or experimental side, combined with your motivation to enter new topics, are welcome.
  • A PhD position (75% E13 TV-L) starting in February 2022 is available for one research group in the ITP. Please have a look at this announcement, apply by November 30, 2021, and indicate your preferred PhD advisor within the ITP.
  • A postdoc position (100% E14 TVöD) will be available in collaboration with the Physikalisch-Technische Bundesanstalt/ National Metrology Institute (PTB) Braunschweig. An official announcement will follow. The starting date can be between April and October 2022.

Currently I am preparing grant applications such that I hope to be able to announce additional positions next year. In addition, I look forward to already hosting excellent young scientists with independent fellowships. As an alumna of the Studienstiftung des deutschen Volkes, the Minerva Foundation and the Humboldt Foundation, I will be happy to support fellowship applications of qualified candidates for these or other fellowships, e.g.

  • International researchers (with a PhD or equivalent by the start of the program) are invited to apply for a Humboldt Research Fellowship of the Alexander von Humboldt Foundation for 2 years (postdocs) or up to 1.5 years (experienced researchers).
  • Israeli Master and PhD students as well as postdocs are in addition invited to apply for the Minerva Fellowship for up to 3 years (PhD students) or 2 years (postdocs), or a Minerva Short-Term Research Grant.
  • Master students of all nationalities looking for PhD funding are invited to apply for a doctoral scholarship of the Studienstiftung or other suitable foundations (e.g. Begabtenförderungswerke) according to their strengths and extracurricular interests.

I explicitly welcome applications from students and scientists of all nationalities, genders and cultural backgrounds.
