Particle basis of Feigin-Stoyanovsky's type subspaces of level $1$   $\tilde{\mathfrak{sl}}_{\ell+1}(\mathbb{C})$-modules
  We construct particle basis for Feigin-Stoyanovsky's type subspaces of level $1$ standard $\tilde{\mathfrak{sl}}_{\ell+1}(\mathbb{C})$-modules. From the description we obtain character formulas.
