מפגש קבוצת התיאוריה של אנרגיות גבוהות: EFT Bootstrap and the pion S-matrix

Zoom: https://us02web.zoom.us/j/83037428657?pwd=Z3hubVhmbEtUYXNDajY1R2pTaWpHdz09

​Abstract: 

The numerical S-matrix Bootstrap exploits the analyticity, crossing and unitarity properties of scattering amplitudes to bound physical observables. 

Low energy constants in EFTs represent a natural target to test those numerical methods. In this talk I will focus on a specific class of massless EFTs which include QCD in the chiral limit. I will show our numerical results and compare them with existing experimental data.
