    Computing four-point functions with integrability, bootstrap and parity symmetry by Andrea Cavaglià, Nikolay Gromov, Michelangelo Preti

    Published 2025-02-01
    “…As this could be a clear obstacle in restoring higher point functions, we studied the problem of bounding directly a 4-point function at generic cross ratio, showing how to adapt for this purpose the numerical bootstrap algorithms based on semidefinite programming. Another tool we are using to further narrow the bounds is a parity symmetry descending from the N $$ \mathcal{N} $$ =4 SYM theory, which allowed us to reduce the number of parameters. …”
