A large sample of possible new physics signatures have been investigated by both ATLAS and CMS within the Simplified Models (SMS) framework. So far the focus has been on supersymmetric simplified models or specific effective theory scenarios. Here we propose to extend the interpretation of some of the experimental results to other Beyond the Standard Model scenarios, with focus on the sea…
During its first run, the LHC has discovered the Higgs boson and provided powerful constraints on new physics. A large number of experimental results has been made public and, during its second data taking run (Run II) an even larger number of analyses is expected. Both ATLAS and CMS have adopted the Simplified Models framework to interpret their results in terms of new physics constraint…
Inverse problems are often defined as the process of determining underlying causal rules from observations. In particle physics, the inverse problem usually refers to inferring the fundamental theory Lagrangian from LHC and other experimental data. This problem is particularly difficult to solve, due to the large number of models leading to similar signals at the LHC. In this project we p…
In the second half of the 20th-century Quantum Field Theory (QFT) was established as the correct formalism for describing the relativistic quantum realm. This project has as its main goal to study basic concepts of QFT. In addition, the student will apply these concepts for the computation of the muon anomalous magnetic moment in a simple extension of the standard model.
Supersymmetric versions of the SO(10) and PQ models are examples of highly motivated extensions of the MSSM (Minimal Supersymmetric Standard Model). In this project we propose the study of these two classes of models considering the experimental results from the Large Hadron Collider (LHC) and from direct and indirect Dark Matter detection experiments. For the study of the cosmology of th…
The release of the first results of the LHC with the complete set of data obtained in 2011 had important consequences for the phenomenology of physics beyond the Standard Model. In particular, evidence for a 125 GeV Higgs has profound implications for supersymmetric models. In recent months the focus of the phenomenology of supersymmetric models has changed from the minimal models studied…
