Descripción del proyecto
Predicciones teóricas más precisas sobre la evolución a múltiples escalas de los fenómenos de colisionador
El Gran Colisionador de Hadrones, un anillo de 27 km de imanes superconductores, es el acelerador de partículas más grande y potente del mundo. En su interior, dos haces de partículas de alta energía que viajan en direcciones opuestas chocan a velocidades cercanas a la de la luz. La investigación fundamental sobre observables críticos en los campos de Higgs y la física de chorros depende de los cálculos teóricos que describen la evolución del sistema. En el proyecto JANUS, financiado por el Consejo Europeo de Investigación, se mejorará la precisión de estos cálculos mediante el establecimiento de conexiones entre dos ámbitos importantes, a saber: las técnicas de resumen y los generadores de fenómenos Monte Carlo de lluvia de partones, que son programas informáticos que simulan los estados finales de colisiones de alta energía hasta el nivel de partículas estables individuales.
Objetivo
For the decades to come, the pioneering investigation of the fundamental laws of nature at the Large Hadron Collider (LHC) and at future collider experiments will rely on the interpretation of complex scattering events by means of accurate theoretical calculations, which are instrumental to find small signals of elusive new phenomena. These calculations must describe the evolution of the system from the few particles produced in the high-energy scattering to the tens or hundreds of low-energy particles observed in the detectors. This proposal aims at transforming the core of our theoretical understanding of such a multi-scale evolution, which nowadays is often too inaccurate to cope with the striking experimental precision. The goal of JANUS is to develop innovative ideas and theoretical methods to advance significantly both approaches to the problem: Resummations and Parton-Shower-Monte-Carlo (PSMC) generators. JANUS will establish a deep connection between the two fields, resulting in novel technology for the accurate modelling of multi-scale effects. Its main objectives are:
- To formulate new theoretical methods to tackle the resummation of complex collider observables in reactions with more than two emitters and scales with state-of-the-art accuracy.
- To lay the theoretical foundations for a new generation of PSMC algorithms, capable of describing accurately the hard scattering and subsequent parton-shower evolution for reactions with different jet multiplicities with a new standard of precision.
This technology will be applied to obtain state-of-the-art theoretical predictions for a broad range of critical observables in the important fields of Higgs and jet physics, enabling their optimal exploration at the LHC and future collider experiments.
