Sabine Riemann

from Wikipedia, the free encyclopedia
Sabine Riemann

Sabine Riemann , b. Schaller , (* 1953 in Aue, Saxony ) is a German physicist who works primarily in the field of experimental elementary particle physics and particle phenomenology.

Childhood and youth

Sabine Riemann spent childhood and adolescence in Pöhla in the Ore Mountains , in Karl-Marx-Stadt and in Berlin . In 1972 she graduated from high school with honors at the advanced high school "Heinrich Hertz" , a special school in mathematics, in Berlin.

Professional background

Riemann studied physics at the Humboldt University in Berlin from 1972 to 1977 . She completed her diploma thesis with the rating "Excellent" in 1977 with Professor Karin Herrmann in the working group of Professor Klaus H. Herrmann in the field of semiconductor physics (now: Inst. F. Crystallography and Materials Research) on a topic about III-V compound semiconductors , " Investigations on pn junctions Pb 1-x Sn x Te ". After her diploma thesis, she worked in research and development in the GDR industry, initially until 1981 in the Berlin incandescent lamp factory BGW of the VEB Kombinat NARVA in Berlin, mainly on problems of the calibration of luminous flux measurements of multi-band fluorescent lamps. After maternity leave and a move to VEB Schwermaschinenbau Heinrich Rau SHR in Wildau, she designed industrial robot controls. The career turning point came with a stay at the international United Institute for Nuclear Research (JINR) in Dubna / Soviet Union (today Russia), where she accompanied her spouse as a "accompanying spouse" from summer 1983 to summer 1987 after a second baby break. A professional activity within the framework of a delegation (today's usage: delegation) was possible in such situations in the GDR, but not provided for here. Nevertheless, she found the opportunity to practice the profession she had learned.

She worked in the laboratory for new acceleration methods ONMU as an experimental physicist in the group of Professor I. Golutvin in the Ajax / Sigma experiment (with the detector assembly in the Institute for High Energy Physics (Protwino) near Serpuchow / Russia). In the Protvino-Pisa-Zeuthen-Sofiya-Dubna collaboration, she worked on a study on Neutrino investigations at the UNK using tagged neutrino beam facility . The UNK accelerator project was ultimately not implemented. During this time her co-authorship in the ZFITTER collaboration was founded. The ZFITTER collaboration develops and maintains the ZFITTER software for standard model predictions of the physics of the Z boson, which is still setting the international standard today. The current software version is 6.44. The ZFITTER software is licensed, but freely available. As a longtime ZFITTER author, Riemann was awarded the JINR Dubna Scientific Prize in 2000. Riemann is co-author of the first calculation for predicting the W boson lifespan in the Standard Model in 1986 and many other phenomenological studies.

After returning to the GDR in 1987, she worked for a short time in the VEB Kombinat Untergrundspeicherbau UGB Mittenwalde. There she worked in Bernd Dorausch's construction group and developed industrial robots for natural gas and oil pipeline construction under extreme climatic conditions. In 1988, Riemann moved to the computing center of the Institute for High Energy Physics (IfH) Zeuthen of the Academy of Sciences AdW of the GDR. She developed and maintained software for the z-chamber of the L3 experiment developed at the IfH at the LEP accelerator at the European Nuclear Research Center CERN. The IfH was founded, managed and shaped over decades by academician Karl Lanius . The institute was dissolved after the fall of the Berlin Wall in 1991 and on January 1, 1992, a state treaty made it part of the German Electron Synchrotron (DESY), Hamburg. Some of the IfH employees were newly hired at DESY. Since then, Riemann has been working in the High Energy Physics department, which is currently headed by Professor Thomas Naumann . She used the opportunity to do a doctorate at RWTH Aachen University under the direction of Professor i. R. Albrecht Böhm and in 1994 defended her doctoral thesis on Search for a Z 'boson at the Z resonance with the L3 detector at the LEP accelerator , which was carried out in the L3 collaboration at the accelerator LEP at CERN in Geneva. The study became the basis of an L3 collaboration publication. The underlying computer program ZEFIT, an interface to the ZFITTER program, is licensed, but freely available. From 1990 until the end of the collaboration, Riemann was a member of the Zeuthen group of the L3 collaboration, which was headed by Nobel Prize winner Samuel Ting . She is involved in several current projects on the precision analysis of accelerator data and the preparation of a new electron-positron accelerator, ILC.

Further projects and teaching

In 1991/1992, Riemann worked for the L3 collaboration at CERN for a year. In addition to the measurements and studies on the physics of the Z boson in the L3 collaboration and in the LEP Electroweak Working Group LEPEWWG and the support of ZFITTER, Riemann has also devoted himself to studies on the search for alternative model scenarios in various electron-positron collider projects. In addition to the above-mentioned articles on the search for heavy gauge bosons, the studies on the analysis of the Z-resonance in the S-matrix theory should be emphasized . The review article "Precision electroweak physics at high energies" in Reports on Progress in Physics summarizes essential results on this and on the verification of the standard model. Riemann later worked again on particle source and detector studies, among others with Peter Sievers (CERN, retired ) and Professor (in Cooperation with DESY) Gudrid Angela Moortgat-Pick for the production of polarized positrons. Together with Professor Wolfgang Friedrich Lohmann, she is responsible for the Linear Collider (LC) group at DESY in Zeuthen in preparation for an electron-positron linear accelerator project. She is co-editor of Volume 2 Physics of the ILC Technical Design Report from 2013. The document may be the basis for the construction of the projected collider in Japan. Riemann regularly takes on lectureships at the University of Potsdam, where he gives courses on nuclear and particle physics as well as lectures on elementary particle physics at the Technical University of Applied Sciences Wildau (TU). She has supervised several diploma and doctoral theses.

Riemann offers summer course lectures at DESY and JINR, among others. She is regularly involved in the organization of specialist conferences, especially at the LC Forum, and has been a co-applicant for EU-funded international research and training networks on several occasions, including in 2013 the European training network "HiggsTools - The Higgs quest - exploring electroweak symmetry breaking at the LHC "in the CORDIS FP7 program. Riemann cooperates, primarily on the subject of radiation protection, with the Photo Injector Test Facility at DESY project, Zeuthen PITZ campus.

Personal

Riemann lives in Königs Wusterhausen and on Usedom . She is married to the German particle physics theorist Tord Riemann and has two adult children.
