WebFeb 3, 2024 · Theorem 1.1 is sufficiently strong to prove that this stronger assumption is satisfied and appears to be the first result in the literature that yields better than Gaussian tails for the \Phi ^4_3 measure. The best bounds obtained using phase cell expansion techniques appear to be slightly worse than Gaussian [ 26, Thm I.3].
