Frontiers in precision phenomenology: Resummation, Amplitudes, and Subtraction

5 Aug 2024, 09:00 → 30 Aug 2024, 18:00 Europe/Zurich

4/3-006 - TH Conference Room (CERN)

This workshop aims to tackle the challenges that we face in view of the anticipated precision from the experiments by facilitating a fruitful exchange between the communities of Resummation, Amplitudes, and Subtractions. The themes of the workshop are:

• Fully differential calculations at NNLO and beyond: local and non-local subtractions.   
• Amplitudes and multiloop techniques for EFT ingredients: resummation beyond NNLL and N³LO counterterms.   
• Going beyond Leading Power: improving subtraction methods with analytic power corrections and Resummation at subleading power.

Organising committee:

• Samuel Abreu (CERN)
• Alexander Huss (CERN)
• Stefan Kallweit (UZH)
• Michelangelo Mangano (CERN)
• Pier Monni (CERN)
• Chiara Signorile–Signorile (MPI)
• Melissa van Beekveld (Nikhef)
• Gherardo Vita (CERN)
• Hua-Xing Zhu (Beijing)
