Abstract

The recently proposed Zcs(3985)− structure is investigated using a first-order tetraquark mass formula. This mass relationship is based on weakly bound Ds−(c-bar s) + D*0(2007)(c u-bar) and Ds*−(c-bar s) + D0(c u-bar) meson clusters and provides a reasonable prediction (within about 3%) of the measured Zcs(3985)− mass.
