We investigate the scalar and pseudoscalar spectrum of the SU(2) gauge
theory with Nf=2 flavours of fermions in the fundamental representation
using non perturbative lattice simulations. We provide first benchmark
estimates of the mass of the lightest 0(0+) (σ), 0(0−)
(η′) and 1(0+) (a0) states, including estimates of the relevant
disconnected contributions. We find ma0/FPS=16.7(4.9),
mσ/FPS=19.2(10.8) and mη′/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
Composi te Higgs-Technicolor theory \cite{Cacciapaglia:2014uja} to models of
composite dark matter.Comment: 18 pages, 9 figure
