DESCRIPTION:Speakers: Maria Polackova (University of Edinburgh)\n\nResearc
 h in scattering amplitudes currently rests on two main pillars: the differ
 ential-equations approach and the analytic bootstrap. Differential equatio
 ns have enabled state-of-the-art predictions for present-day collider expe
 riments\, with recent developments pushing towards three-loop QCD correcti
 ons. At the same time\, conventional differential-equation methods face th
 e challenge of finding simpler bases of master integrals and bringing the 
 corresponding differential equations into an epsilon-factorised form. The 
 analytic bootstrap offers a complementary and potentially transformative p
 ath forward. Its central idea is to exploit constraints on scattering ampl
 itudes from fundamental principles such as analyticity\, causality\, local
 ity\, and unitarity. Together\, these principles drastically restrict the 
 space of functions an amplitude can evaluate to\, allowing us to tackle c
 ases where traditional methods become prohibitively difficult. A central r
 ole in this program is played by the Landau equations\, which determine t
 he singularity structure of Feynman integrals. In this talk\, I will revie
 w recent progress on the Landau bootstrap of Feynman integrals and show ho
 w these methods can be applied beyond Feynman integrals.\n \n\nhttps://in
