 Obiettivo del progetto (Objective)

'This project is concerned with the characterization of the physics associated with the moduli stabilization and supersymmetry breaking at a TeV scale in String Theory compactifications. Although a lot of progress has been made, a complete picture of the low energy physics of String Theory is still far from being achieved. We plan to improve our understanding of several unexplored aspects which may help to establish a possible link with the experiments. Concretely, we propose to research the phenomenological properties of the recently discovered generalized structures. These turn out to be the natural objects for compactifying the theory to four dimensions, generalizing the Calabi-Yau case, and constituting a perfect framework for flux compactifications. We want to engineer the non-supersymmetric deformations and to identify the patterns of soft supersymmetry breaking arising at low energies. This also involves a better understanding of the non-perturbative physics induced by stringy instantons, and how these could affect the perturbative physics. The deepening into these issues is clearly related to some of the most pressing problems in String Theory.'

Introduzione (Teaser)

As particle accelerators come of age, a new paradigm for explaining the physics behind them and behind their experiments is needed.

Descrizione progetto (Article)

The philosophy and intricacies behind high-energy physics are generally being explained by what is known as the Standard Model (SM), which explains all interactions in nature.

In large particle accelerators, SM cannot be applied to all the emerging observations and a new model is needed to explain the physics behind these accelerators. These include changes in gravitational interaction, cosmological variations, accelerated expansion and other phenomena seen in such settings. The EU-funded project 'Phenomenology of strings: generalized structures, non-perturbative physics and supersymmetry breaking' (String Pheno) attempted to elaborate this new model.

The project investigated how String Theory fits with accelerator physics in how it covers particles and interactions in nature under a unified framework (gravity, gauge interactions and supersymmetry). String Theory is particularly important in light of the Large Hadron Collider (LHC) accelerator, which recently went online. The LHC instrument allowed the project to explore some of the mysteries of low-energy physics, focussing in particular on the mechanisms for supersymmetry breaking and moduli stabilisation.

Under the latter subject, the project team conducted numerous experiments to advance the field of String Theory. The field of study undertaken is also known as compactification of String Theory.

All the experiments were documented and can help scientists unravel the intricacies and secrets of String Theory, thus advancing research in this area considerably.
