“…In λφ 4 theory, the lowest decay exponent is O( √ λ), which is indeed a non-perturbative result. Several works, including [3,4,5,6,7,8,9,10,11,12,13,14,15,16], have explored various aspects of the problem over the years. Among them [11] has been particularly illuminating to the author and answers the Poincaré patch version of our main question.…”
