XQCDBaryons

EUFLAG

XQCD Baryons was a Marie Skłodowska Curie Individual Fellowship project, funded by the European Union's Horizon 2020 research and innovation programme under grant agreement number 744659 from 2017 until 2019.

The Fellowship enabled Dr. Madanagopolan Padmanath to carry out research at Universität Regensburg during this period.

The research resulted in the following scientific publications.

Brief description of the research:

Quantum chromodynamic (QCD) is a part of the Standard Model of elementary particles and their interactions. It is this theory that governs the strong interactions between quarks and gluons. At very large momentum scales (or small distances), the QCD coupling parameter becomes small and perturbative expansion is applicable. QCD has been tested throughly in this regime. However, at somewhat larger distances the strong interactions bind quarks and gluons into hadrons, such as the pion and the proton. This is the region where numerical simulation of the underlying theory (lattice QCD) is required. Experimentally there was a lot of progress recently, discovering new resonances that contain a charm quark and a charm antiquark (charmonia). More recently, at the LHCb at CERN, new baryons containing two charm quarks and a light quark have been discovered as well as many baryons containing the even heavier bottom quark. The properties of these particles and resonances need to be derived from QCD, which then will also guide experimental searches. An understanding of the world of elementary particles and of our place in the world is important for society as a whole. The objectives of this project are mainly to develop calculational techniques that enable us to do so but also to achieve some predictions that can directly be compared to experiment.
