In most models beyond the Standard Model, new particles have very short lifetimes. This leads to having the new particle decaying before it can travel a macroscopic distance, such that the only way of detecting it is by measuring its decay products.

A long-lived particle has a much longer lifetime, and is capable of travelling measurable distances before it decays. Detection of such a particle in a collider can be difficult, as experiments are not originally designed for these non-standard signatures.

This research project, funded by CONCYTEC, aims to study the phenomenology of neutral long-lived particles at the LHC. Such a scenario can arise in certain realizations of models that generate neutrino masses.

The project will fund four undergraduate thesis, as well as cover the computing costs within an Amazon Web Service framework.
