Loop-the-Loop: Feynman Calculus and its Applications to Gravity and Particle Physics

“Loop-the-Loop: Feynman Calculus and its Applications to Gravity and Particle Physics” returns for its third edition, and for the first time it will be an in-person conference at Scuola Normale Superiore, Pisa, Italy, on 16-20 November 2026. This year we expand to five days, consisting of a two-day school followed by a three-day workshop. The event aims to spark in-depth discussions and strengthen connections across complementary perspectives in the study of scattering amplitudes.

The school during the first two days will consist of three lecture series, curated by field-leading specialists:

• Asymptotic Expansions in Multi-Loop Calculations
• Worldline Quantum Field Theory for Post-Minkowskian Gravity
• Cosmological Correlators

The following three day workshop will be centred around the three topics:

• Applied Mathematics for Feynman Calculus and Particle Physics
• Amplitude Methods for Gravitational Wave Physics
• Cosmological Correlators

These will include review seminars by leading experts in their respective fields.

Virtual Attendance
For those who are unable to attend in-person, we also offer the usual virtual format. We will display the Zoom details here.
