''' Research description '''
 
 
 
The LHC is a "top quark factory": more than 1 million top quark
 
pairs are produced every year. Such large data sets give the
 
opportunity to study top quark production and decay in great detail.
 
New physics, such as 4th generation top-like quarks, or supersymmetric
 
partners of the top quark, may lead to final states in the detector
 
that look like top quark pairs, but are subtly different.
 
A number of variables are suited to probe possible differences between
 
Standard Model top quark production, and new physics. These include
 
variables related to the missing energy in the event, but also other
 
kinematic variables have been proposed.
 
The goal of this master project is to study these variables in
 
detail: what do they measure exactly and why are they sensitive?
 
This will be done on simulated events, both representing SM top quark
 
production and new physics production. Then, the knowledge gained
 
will be applied to the ATLAS data of 2011 and 2012. If a deviation
 
of SM-like behaviour is found, further studies will need to be done
 
to estimate whether this is due to ununderstood detector behaviour,
 
incomplete simulation of SM top quark pair production, or new physics.
