    Notes: Abstract We bound the large order behavior of these pieces of the renormalized perturbation expansion for ρ 4 4 which do not contain “renormalons” [1]. The bound we obtain has the form of the leading asymptotic behavior computed by the Lipatov method, with the exact value of the “Lipatov constant.” Therefore, this paper is a step towards the rigorous study of the large order behavior of Φ 4 4 and towards a proof of existence of the first “renormalon” singularity which should prevent the theory from being Borel summable. Using the results of this paper and the techniques of [15], one can for instance improve [17] the estimate [18] on the finiteness of the radius of convergence of the Borel transform of renormalized Φ 4 4 and obtain that this radius is at least the exact value conjectured in [1].
