Description
Experimental results for moments of the leptonic $q^2$-spectrum in inclusive semileptonic B-meson decays often involve cuts on $q^2$. Therefore, the spectrum itself (rather than its moments only) needs to be evaluated on the theoretical side. We present results of our calculation of $\mathcal{O}(\alpha_s^2)$ corrections to this spectrum that have been obtained via a numerical solution to differential equations for the relevant master integrals. Our findings agree with the recently published analytical results of Fael and Herren.
