The acylindrical hyperbolicity conjecture for Artin groups

Let $A_S$ be an Artin group, and let $Z_S$ denote the centre of $A_S$. Acylindrical hyperbolicity conjecture. The quotient $A_S/Z_S$ is acylindrically hyperbolic. This would provide a broad criterion for acylindrical hyperbolicity among Artin groups, a property that remains open in general.
