The Waring Support Rank of the Elementary Symmetric Polynomials

Definition. The Waring rank of a homogeneous polynomial $f \in C[x_1, \ldots, x_n]_d$ is the minimum $r$ such that

for some linear forms $\ell_1, \ldots, \ell_r \in C[x_1, \ldots, x_n]_1$.

Problem. Give asymptotic bounds on A(n,d), the minimum Waring rank among all polynomials in $C[x_1, \ldots, x_n]_d$ whose support is the set of all squarefree monomials of degree $d$ in $n$ variables.
