We present a derivation of nonperturbative corrections to SCET-II-type observables in the large-$\beta_0$ approximation based on the bubble-sum approximation within the SCET framework. We demonstrate how to obtain the leading-power nonperturbative corrections using the collinear anomaly approach and further discuss their impact on the corresponding partonic cross sections.

Previous studies have shown that certain observables at massless $e^+e^−$ colliders producing primary top quarks can be used to measure the top quark mass with an uncertainty smaller than $\Lambda_{\rm QCD}$. The maximal sensitivity to the top mass is attained in the peak of the distribution, where Effective Field Theories (EFTs) enable the factorization of the differential cross section...
