] | We discuss interacting, closed, bosonic and superstrings in thermal equilibrium at temperatures close to the Hagedorn temperature in flat space. We calculate S-matrix elements of the strings at the Hagedorn temperature and use them to construct a low-energy effective action for interacting strings near the Hagedorn tem... |

fermions, including determination of fixed points and curves that separate
regions of different flow behavior. We assess the reliability of perturbative
calculations for various values of Yukawa coupling $y$ and quartic scalar
coupling $\lambda$ by... | [
