Descrizione del progetto
Una nuova struttura per studiare i fenomeni al di là del modello standard
La scoperta di una particella o di interazioni nuove nel Large Hadron Collider (LHC) intensificherebbe la ricerca nel campo della fisica al di là del modello standard. Il successo di tali sforzi si basa su dati sperimentali ad alta precisione e previsioni teoriche, nonché sull’esistenza di una solida struttura per interpretare a livello globale tutte le possibili sottili deviazioni dalle previsioni del modello standard. Il progetto PBSP, finanziato dall’UE, si concentrerà sullo sviluppo di tale struttura. La ricerca riguarderà diverse aree della fisica delle particelle, quali le strutture protoniche e le teorie dei campi quantistici efficaci, e includerà uno studio completo della fenomenologia del modello standard. Il progetto mira a dimostrare che l’interazione tra nuove ricerche e la struttura non perturbativa dei protoni in collisione è essenziale per sfruttare appieno il potenziale della fisica dell’LHC.
Obiettivo
The Large Hadron Collider (LHC) at CERN is leading the exploration of the high-energy frontier. Its high-luminosity phase is just around the corner and the validity of our current theory of elementary particles, the Standard Model (SM), will be probed to an unprecedented level. The hunt for physics beyond the SM will be pursued via direct searches of new particles that are light enough to be produced at the LHC. At the same time new physics could manifest itself indirectly through deviations from SM theoretical predictions, induced by new particles whose masses are well above the scale probed by the LHC. The success of indirect searches requires the highest possible level of precision in three complementary components: experimental data, theoretical predictions and - crucially - a robust framework to globally interpret all subtle deviations from the SM predictions that might arise.
PBSP will provide such a framework by:
1. quantitatively establishing whether high-scale new physics effects can be mimicked by low-scale non-perturbative physics, and therefore inadvertently absorbed into the parametrisation of the proton structure
2. devising a new framework to deliver a global fit of a model-independent parametrisation of high-scale new physics, including several datasets that provide complementary experimental information
3. expanding such a framework to exploit the precise LHC measurements to constrain simultaneously the structure of the proton and new physics degrees of freedom
PBSP involves several areas of particle physics, ranging from fits to the proton’s structure to effective quantum field theories and a comprehensive study of beyond the SM phenomenology. My ERC-funded project will demonstrate that the interplay between indirect new physics searches and the knowledge of the non-perturbative structure of colliding protons is essential to fully exploit the LHC physics potential.
