Field of Interest:hep-ex
Experiments:CERN-LHC-ATLAS
Deadline: 2017-09-01
Region: Europe
Job description:
Workplan:
The postdoctoral researcher will be based half in Orsay, half in Saclay for periods of 12 months. (S)he will work on the W mass measurement in the ATLAS experiment, and more specifically on experimental efforts like hadronic recoil calibration. Two different algorithms will be used at 8 and 13 TeV due to the differences in reconstruction and pile-up conditions, justifying to spend a full year on this in Saclay.
(S)he will also be involved in pdf profiling studies, physics modeling and unfolding. It should be possible to simultaneously profile the pdf’s and extract mW, therefore benefitting from a reduced uncertainty. This will need to entirely revisit the fitting strategy and requires the development of a new software. The estimated timescale for this is a full year spent at LAL.
The postdoctoral researcher will have a big visibility in the field, interacting with the scientific community in the Paris area and at CERN. (S)he will have developed skills interesting for the industry as well at the end of the contract (big data handling, optimisation of reconstruction algorithms, …).
Scientific Environment:
The Saclay W mass team is composed of F. Balli, M. Boonekamp and N. Besson. This team has one PhD student under its supervision, working on electroweak physics. The Orsay W mass team is composed of L. Fayard, M. Kado and Z. Zhang. Both teams have successfully supervised a large number of students in the past, among which several contributed significantly to the 7 TeV W mass measurement. The ATLAS groups to which the teams belong have a typical size of about 30 permanent physicists each and have had strong contributions to the experiment.
The postdoctoral researcher will also interact with the ATLAS Standard Model group and will make regular trips to CERN.
How to apply : Candidates should send a CV, a brief statement of research interests and arrange to have at least three letters of reference sent to Fabrice Balli (fabrice.balli@cern.ch) and Zhiqing Zhang (zhangzq@lal.in2p3.fr)
Starting date : The position starts in Automn 2017, preferably in October ; some flexibility is possible (to be discussed).
Deadline : Applications received by September 1st, 2017 will receive full consideration. The call will remain open until filled.
More information : For further information on the project, please contact the following physicists contributing to the project : Fabrice Balli (fabrice.balli@cern.ch) and Zhiqing Zhang (zhangzq@lal.in2p3.fr) , Nathalie Besson (nathalie.besson@cea.fr), Maarten Boonekamp (maarten.boonekamp@cern.ch), Louis Fayard (fayard@lal.in2p3.fr) and Marumi Kado (kado@lal.in2p3.fr)
