Description
We calculate the low-energy constant $L_{10}$ in an SU(4) lattice gauge theory
with dynamical fermions in two representations. This theory is close to a particular composite-Higgs model. From this, we obtain the contribution of the new strong sector to the S parameter. The resulting upper bound on the vacuum misalignment parameter $\xi$ is similar to current estimates for this bound. We outline future directions for lattice calculations in near-conformal composite-Higgs models.
