We modify the Starobinsky inflation model by adding the Bel-Robinson tensor $T^{\\mu\\nu\\lambda\\rho}$ squared term proposed as the leading quantum correction inspired by superstring theory. The $(R+\\frac{1}{6m^2}R^2 -\\frac{\\beta}{8m^6}T^2)$ model under consideration has two parameters: the inflaton mass $m$ and the string-inspired positive parameter $\\beta$. We derive the equations of motion in the Friedmann-Lemaitre-Robertson-Walker universe and investigate its solutions.
