  "abstract": "We calculate the low-energy tunneling density of states $\\nu(\\epsilon, T)$ of an $N$-channel disordered wire, taking into account the electron-electron interaction non-perturbatively. The finite scattering rate $1/\\tau$ results in a crossover from the Luttinger liquid behavior at higher energies, $\\nu\\propto\\epsilon^\\alpha$, to the exponential dependence $\\nu (\\epsilon, T=0)\\propto \\exp{(-\\epsilon^*/\\epsilon)}$ at low energies, where $\\epsilon^*\\propto 1/(N \\tau)$. At finite temperature $T$, the tunneling density of states depends on the energy through the dimensionless variable $\\epsilon/\\sqrt{\\epsilon^* T}$. At the Fermi level $\\nu(\\epsilon=0,T) \\propto \\exp (-\\sqrt{\\epsilon^*/T})$.",
