Letbe the single-electron fiber Hamiltonians of the massless Nelson model at total momentumPand infrared cut-off. We establish detailed regularity properties of the correspondingn-particle ground state wave functionsas functions ofPand. In particular, we show that \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\begin{aligned} \ \ |\partial _{P^j}f^{n}_{P,\sigma }(k_1,\ldots , k_n)|, \ \ |\partial _{P^j} \partial _{P^{j'}} f^{n}_{P,\sigma }(k_1,\ldots , k_n)| \!\le \! \frac{1}{\sqrt{n!}} \frac{(c\lambda _0)^n}{\sigma ^{\delta _{\lambda _0}}} \prod _{i=1}^n\frac{ \chi _{[\sigma ,\kappa )}(k_i)}{|k_i|^{3/2}}, \end{aligned}$$\end{document}wherecis a numerical constant,is a positive function of the maximal admissible coupling constant which satisfiesandis the (approximate) characteristic function of the energy region between the infrared cut-offand the ultraviolet cut-off. While the analysis of the first derivative is relatively straightforward, the second derivative requires a new strategy. By solving a non-commutative recurrence relation, we derive a novel formula forwith improved infrared properties. In this representationis amenable to sharp estimates obtained by iterative analytic perturbation theory in part II of this series of papers. The bounds stated above are instrumental for scattering theory of two electrons in the Nelson model, as explained in part I of this series.
