-This is an overview with all available bachelor student projects in the Nikhef ATLAS group.
-If you have your own research proposal, need more detailed information on the (availability) of individual proposals or would like to discuss about other available projects in the group you are always welcome to contact either the contact person for the project and/or the Nikhef ATLAS group leaders:

-''' Research description: '''
-In dit project wordt de spin van het top-quark bestudeerd. Recentelijk is het top-quark is bij de
-LHC waargenomen in botsingen tussen twee protonen, waarbij een enkel top-quark is geproduceerd
-door fusie van een W-boson en een b-quark. Het top-quark is daarbij uiteen gevallen, via het
-geschikt om de spin van de top-quark te achterhalen, via bepaling van een aantal hoeken in de
-vervals-producten.
-Voor deze analyse zijn verschillende methoden mogelijk, die ieder een eigen gevoeligheid hebben
-voor de spin van het top-quark. Tijdens dit project zullen we de verschillende methoden
-onderzoeken; waarbij de methoden zich onderscheiden door de hoeken vanuit verschillende Lorentz
-systemen te bekijken.
-Tijdens dit project zul je je eigen reconstructie van de botsingen maken, om daarmee te
-achterhalen hoe daarop het beste de spin-richting van het top-quark kan worden bepaald. Dit kan
-vervolgens met de ATLAS data worden vergeleken, indien de tijd dat toestaat.

-''' Supervisors:'''  Ivo van Vulpen (staf) and Antonio Castelli (PhD student)
-''' Research description: '''
-The ATLAS detector allows to measure the mass of the
-Higgs boson, recently discovered in 2012.
-This measurement is a crucial test for the validity of the
-Standard Model, the theory that describes the interaction
-among elementary particles.
-The student will be guided through the strategy of the
-measurement of the Higgs boson mass from the measurement
-of the mass of the four leptons produced in one of its possible
-decay.
-The student's task will be to study the impact of the er-
-ror distribution of the four leptons mass in the final mea-
-surement of the Higgs mass. In order to do that he/she will
-learn the fundamental notions of statistical data analysis us-
-ing the ROOT software. He/she will then be asked to study
-the simulated ATLAS data to understand the main sources of
-uncertainty on the momentum of the reconstructed particles.
-Schedule
-week 1: Small introduction about theory and ATLAS experiment
-week 2: Introduction to ROOT and Higgs to four lepton event selection
-week 3/4: Creation and study of four lepton distribution of mass and error
-week 4/5: Creation and study of four lepton distribution of mass and error
-week 6/7: Closer look at events with large error, where does it come from?
-week 8/9: Closer look at events with large error, where does it come from?
-week 10: Presentation of the results
-week 11: Writing and discussion
-week 12: Writing and discussion
