We provide first benchmark estimates of the mass of the lightest $0(0^{+})$ ($sigma$),
$0(0^{-})$ ($eta’$) and $1(0^+)$ ($a_0$) states, including estimates of the relevant disconnected contributions.
We find $m_{a_0}/fps= 16.7(4.9)$, $m_sigma/fps=19.2(10.8)$ and $m_{eta’}/fps = 12.8(4.7)$. These values for the masses of light scalar states provide crucial information for composite extensions of the Standard Model from the unified Fundamental Composite Higgs-Technicolor theory to models of composite dark matter.
