I am a Ph.D. student in the Warwick LHCb group supervised by Dr. Thomas Blake and Dr. Michal Kreps.

LHCb commissioning

In 2022, the LHC restarts after several years of shut-down. During the break, a lot of the LHCb detector was upgraded for the higher luminosity of the LHC in the future. I am currently helping to commission our upgraded detector.

Flavour physics workshop

In April 2022, I presented my studies related to Λb→pK-μ+μ- in the Flavor at the CrossroadsLink opens in a new window Workshop in Mainz (Germany).

Warwick Three Minute Thesis final 2021

I participated in Warwick's internal Three Minute Thesis competition where PhD students summarize their PhD project in three minutes aimed at the general public. The title of my presentation was:
Particle post and messenger pigeons - How do fundamental particles interact?

Main project: rare decays at LHCb: Λb→pK-μ+μ-

The Standard Model of particle physics has been the dominant theory of elementary particles and their interactions since its development around 50 years ago. But the evermore precise measurements of recent years deviate from the Standard Model predictions. These deviations possibly caused by New Physics are small. And because it may be easier to find the needle in a small hay stack, physicists look for New Physics in decays that are rare (instead of abundant) in the Standard Model.

The decay of a bottom quark to a strange quark and two oppositely charged muons, b→sμ+μ-, is a very commonly studied rare decay. Due to colour confinement though, this quark-level transition can never be observed directly. Instead, physicists must look at decays of a b hadron to an s hadron, like in my case Λb→Λ*μ+μ-. Because the Λ* resonance decays instantly, we can only see its children, a proton and a kaon, in the detector. A special feature of the decay Λb→pK-μ+μ- is that there are many Λ* resonances that are difficult to disentangle experimentally.

What happened previously

I grew up in the Allgäu region in the South of Germany and obtained my B.Sc. and M.Sc. degrees in physics from TU Dortmund. Between those degrees, I studied for one year at Umeå Universitet and participated in the DESY Summerschool working on thermal resilience tests for a new tracking detector to be installed in the ATLAS upgrade for the LHC high-luminosity phase. For my master thesis, I was part of Johannes Albrecht's group analysing Λb→pK-ɣ decays at LHCb in collaboration with researchers at IJCLab Orsay where I spent several months during the research phase.
