Particle Physics with ATLAS at the LHC
Our research focus is on particle searches with the ATLAS detector at the LHC using signatures with tau lepton decays and electrons in the final state. The data analyses are mainly
- Search for heavy neutral Higgs bosons, heavy gauge bosons and massive resonances decaying into pairs of tau leptons
- Development of new reconstruction methods for hadronic tau leptons and electrons and measurement of their efficiencies and related background contributions to physics processes
We have long-term expertise in reconstruction and identification of hadronic tau decays for isolated and boosted decay topologies, as well as measurement of electrons with the ATLAS detector. Our group members contribute to the ATLAS core software packages to implement new reconstruction algorithms and analyses techniques. We use advanced statistical methods for hypothesis testing and for multivariate data analysis, like boosted decision trees, artificial neural networks and deep-learning techniques.
The Run 3 of LHC is currently ongoing and will continue until mid 2026. We will use the corresponding ATLAS data to explore new physics phenomena beyond the Standard Model.
