News from our group
Martin Sobotzik successfully completed his doctoral thesis on Angular Analysis of the B → K*ℓℓ Decay in Long Shutdown 1 Data at Belle II.
In his analysis he is looking for signs of physics beyond the standard model in flavour-changing neutral currents (FCNC) where a B meson decays into a kaon and two leptons. Since this decay can only occurr in loop diagrams, it is heavily suppressed.
He therefore investigated the use of neural networks to select these rare events from Belle II data collected until the Long Shutdown 1. Furthermore, using advanced statistical tools, he could improve the background subtraction compared to the traditional approach of extracting the background shape from simulations, thus decreasing systematic effects.
Congratulations!
The new Collaborative Research Center (CRC) 1660 “Hadrons and Nuclei as Discovery Tools” at JGU wants to give doctoral students the opportunity to conduct research in an attractive and international environment together with renowned scientists.
For the CRC Fellowships application call in 2025, we are looking for PhD candidates for our projects "N01: Neutron-skin and surface-thickness of 208Pb" and "N02: Study of reaction cross sections of astrophysical interest".
For more details, please go to CRC 1660 PhD Announcements. Deadline for applications is February 28th, 2025.
Our paper, drafted and submitted by Anselm Esser, on the newly developed FPGA-based readout system for asymmetry measurements at A1 has been published in NIM A.
Congratulations to everyone involved for their help!
