A generalization of the Powers-Størmer-Ogata inequality

We show that for any positive operator monotone function $f$ the inequality $\int_{[0,\infty)} f(t) \, \mathrm{d} \left\lVert E^{Δ_{φ,ψ}}(t) ξ_ψ\right\rVert^2 + f'_\infty φ(1-s(ψ)) \geq \frac{f(1)}{2} \Bigl( φ(1) + ψ(1) - \lVert φ- ψ\rVert \Bigr)$ holds, where $φ, ψ\in \mathcal{M}_{*,+}$ are two nor
