Description
FIPs (Feebly Interacting Particles) are proposed entities that can
explain dark matter and the non-observation of such states at accelerators:
The reason they have not yet been seen is rather than that they are too massive
(the explanation of non-observation of SUSY), they are too feebly interacting to
have been observed at LHC or LEP. Future e+e- machines opens up new ways to
search for such states: while still having the same low-background conditions
and known initial state as at LEP, the future machines will feature 1000 times
higher luminosities compared to LEP.
FIPs could manifest themselves in different ways. This project intends to
study one possibility, namely that the new particle can decay into detectable
standard model (SM) particles, but are so weakly coupled that these decays happens
at macroscopic distances from their production point,so called Long Lived Particles,
LLPs. In the project, it will be assumed that the FIP itself is not detectable.
The project requires full detector simulation of such signals, using the available tools,
but modifying aspects of the signal to evaluate the performance for different FIPs decay-lengths
and decay modes. These simulated events should then be analysed with the tools at hand. For
the latter part, the student can profit from collaboration with the student of another
project proposed by our group ("V0-Finding at a Future Higgs Factory").
