QCD worldsheet axion from the bootstrap
Andrea Guerrieri, Victor Gorbenko
The worldsheet axion plays a crucial role in the dynamics of the Yang-Mills confining flux tubes. According to the lattice measurements, its mass is of order the string tension and its coupling is close to a certain critical value. Using the S-matrix Boots ...
New York2024S-matrix bootstrap for effective field theories: massless pions
We use the numerical S-matrix bootstrap method to obtain bounds on the two leading Wilson coefficients (or low energy constants) of the chiral lagrangian controlling the low-energy dynamics of massless pions. This provides a proof of concept that the numer ...
SPRINGER2021Flux Tube S-Matrix Bootstrap
Andrea Guerrieri, Aditya Hebbar
We bootstrap the S matrix of massless particles in unitary, relativistic two dimensional quantum field theories. We find that the low energy expansion of such S matrices is strongly constrained by the existence of a UV completion. In the context of flux tu ...
AMER PHYSICAL SOC2019Bootstrapping QCD Using Pion Scattering Amplitudes
We consider the S-matrix bootstrap of four-dimensional scattering amplitudes with O(3) symmetry and no bound states. We explore the allowed space of scattering lengths which parametrize the interaction strength at threshold of the various scattering channe ...
