  "abstract": "The $p p \\to n K^+ \\Sigma^+(1385)$ reaction is a very good isospin $3/2$ filter for studying $\\Delta^{++*}$ resonance decaying to $K^+\\Sigma^+(1385)$. Within the effective Lagrangian method, we investigate the $\\Sigma(1385)$ (spin-parity $J^P = 3/2^+$) hadronic production in the $\\pi^+ p \\to K^+ \\Sigma^+(1385)$ and $p p \\to n K^+ \\Sigma^+(1385)$ reactions. For $\\pi^+ p \\to K^+ \\Sigma^+(1385)$ reaction, in addition to the \"background\" contributions from $t$-channel $K^{*0}$ exchange, $u$-channel $\\Lambda(1115)$ and $\\Sigma^0(1193)$ exchange, we also consider the contribution from the $s$-channel $\\Delta^*(1940)$ resonance, which has significant coupling to $K\\Sigma(1385)$ channel. We show that the inclusion of the $\\Delta^*(1940)$ resonance leads to a fairly good description of the low energy experimental total cross section data of $\\pi^+ p \\to K^+ \\Sigma^+(1385)$ reaction. Basing on the study of $\\pi^+ p \\to K^+\\Sigma^+(1385)$ reaction and with the assumption that the excitation of $\\Delta^*(1940)$ resonance dominant the $pp \\to n K^+ \\Sigma^+(1385)$ reaction, we calculate the total and differential cross sections of $p p \\to n K^+ \\Sigma^+(1385)$ reaction. It is shown that the new experimental data support the important role played by the $\\Delta^*(1940)$ resonance with a mass in the region of $1940$ MeV and a width of around $200$ MeV. We also demonstrate that the invariant mass distribution and the Dalitz Plot provide direct information of the $\\Sigma^+(1385)$ production, which can be tested by future experiments.",
