Query: Riesz transforms characterizations of Hardy spaces $H^1$ for the
  rational Dunkl setting and multidimensional Bessel operators   We characterize the Hardy space $H^1$ in the rational Dunkl setting
associated with the reflection group $\mathbb Z_2^n$ by means of Riesz
transforms. As a corollary we obtain a Riesz transform characterization of
$H^1$ for product of Bessel operators in $(0,\infty)^n$.
