Journal Article
Rauh, T. (2018). Higher-order condensate corrections to ϒ masses, leptonic decay rates and sum rules. Journal of High Energy Physics, 2018(05), Article 201. https://doi.org/10.1007/jhep05%282018%29201

With the recent completion of NNNLO results, the perturbative description of the ϒ system has reached a very high level of sophistication. We consider the non-perturbative corrections as an expansion in terms of local condensates, following the appro...

Non-resonant and electroweak NNLO correction to the e+e− top anti-top threshold (2018)
Journal Article
Beneke, M., Maier, A., Rauh, T., & Ruiz-Femenía, P. (2018). Non-resonant and electroweak NNLO correction to the e+e− top anti-top threshold. Journal of High Energy Physics, 2018(2), Article 125. https://doi.org/10.1007/jhep02%282018%29125

We determine the NNLO electroweak correction to the e+e−→bb¯¯W+W−X production cross section near the top-pair production threshold. The calculation includes non-resonant production of the final state as well as electroweak effects in resonant top ant...

Reconstruction of top-quark mass effects in Higgs pair production and other gluon-fusion processes (2018)
Journal Article

We propose a novel method for the treatment of top-quark mass effects in the production of H(∗), HH, HZ and ZZ final states in gluon fusion. We show that it is possible to reconstruct the full top-quark mass dependence of the virtual amplitudes from...

Dimension-six matrix elements for meson mixing and lifetimes from sum rules (2017)
Journal Article
Kirk, M., Lenz, A., & Rauh, T. (2017). Dimension-six matrix elements for meson mixing and lifetimes from sum rules. Journal of High Energy Physics, 2017(12), Article 68. https://doi.org/10.1007/jhep12%282017%29068

The hadronic matrix elements of dimension-six ∆F = 0, 2 operators are crucial inputs for the theory predictions of mixing observables and lifetime ratios in the B and D system. We determine them using HQET sum rules for three-point correlators. The r... Read More about Dimension-six matrix elements for meson mixing and lifetimes from sum rules.
