Hierarchically hyperbolic groups, products of $\textrm{CAT(-1)}$ spaces, and virtual torsion-freeness
Hierarchically hyperbolic groups, products of $\textrm{CAT(-1)}$ spaces, and virtual torsion-freeness
We prove that a group acting geometrically on a product of proper minimal $\textrm{CAT}(-1)$ spaces without permuting isometric factors is a hierarchically hyperbolic group. As an application we construct hierarchically hyperbolic groups which are not virtually torsion-free.

Abstract
We prove that a group acting geometrically on a product of proper minimal $\textrm{CAT}(-1)$ spaces without permuting isometric factors is a hierarchically hyperbolic group. As an application we construct hierarchically hyperbolic groups which are not virtually torsion-free.
