Miró, J. E. & Guerrieri, A. ORCID: 0000-0003-3370-3135 (2021). Dual EFT bootstrap: QCD flux tubes. Journal of High Energy Physics, 2021(10), article number 126. doi: 10.1007/jhep10(2021)126

Abstract

We develop a bootstrap approach to Effective Field Theories (EFTs) based on the concept of duality in optimisation theory. As a first application, we consider the fascinating set of EFTs for confining flux tubes. The outcome of our analysis are optimal bounds on the scattering amplitude of Goldstone excitations of the flux tube, which in turn translate into bounds on the Wilson coefficients of the EFT action. Finally, we comment on how our approach compares to EFT positivity bounds.
