PhD student position within the ATLAS experiment at the CERN Large Hardon Collider at University of Uppsala

Scholarshipat the Department of Physics and Astronomy. Starting date: Spring term 2011.

The Uppsala ATLAS group is part of the High Energy Physics group at the Department of Physics and Astronomy, and currently consists of three faculty members, one post-doctor and three graduate students.

We are looking for an excellent and highly motivated PhD student with keen interest in experimental physics and competence within data analysis programs (e.g. C++ and ROOT). The PhD student will work on physics analysis of data from ATLAS and take part in the development of tools for distributed analysis on the grid needed for this purpose.

The PhD position is funded for four years, extendible to a maximum of five years including department duties at a level of at most 20% (typically teaching). Further information: Visit Official Website. The rules governing this are set out in the Higher Education Ordinance Chapter 5, § § 1-7, and the university`s rules and guidelines Official Website.

After more than 20 years of planning and build-up the Large Hadron Collider (LHC) at CERN in Geneva is now in operation since one year, marking the start of a highly exciting program of investigations deep into micro cosmos. The plan is to run LHC almost continuously during 2011 and 2012 with a successively increasing luminosity, accumulating a sufficient amount of data to make possible, according to current theoretical expectations, the discovery of the Higgs boson and supersymmetric particles.

The ATLAS experiment is the largest detector ever built for particle physics research. The Uppsala ATLAS group has participated in the development and build-up of the Silicon micro-strip detector that is part of the central detector measuring the particle trajectories in ATLAS. We are participating in the operation of ATLAS as well as in the computer analysis of the data that is now collected by ATLAS.

The group`s main physics interest is to search for the charged Higgs boson. The Standard Model of particle physics predicts the existence of only one neutral Higgs boson. The discovery of a charged Higgs boson in the LHC data will prove that the Standard Model must be replaced by a more general theory, like e.g. a Supersymmetric theory, which predicts the existence of both neutral and charged Higgs. We are currently testing various methods of how to extract a charged Higgs signal from the background in the data.

When LHC is in full operation there will be about one billion proton-proton collisions per second, out of which 200 collisions per second will be stored for detailed physics analysis. As every collision produces about 100 megabyte of information in ATLAS, we need an enormous data analysis capacity for the treatment of this data flow. For this we make use of the Worldwide LHC Computing Grid (WLCG), a network of computers distributed over the world. To provide a high analysis capacity to our group, we are participating in the current development of the grid technology.
