Bothmann, E., Flower, L., Gütschow, C., Höche, S., Hoppe, M., Isaacson, J., Knobbe, M., Krauss, F., Meinzinger, P., Napoletano, D., Price, A., Reichelt, D., Schönherr, M., Schumann, S., & Siegert, F. (2024). Event generation with Sherpa 3. Journal of High Energy Physics, 2024(12), Article 156. https://doi.org/10.1007/jhep12%282024%29156

Sherpa is a general-purpose Monte Carlo event generator for the simulation of particle collisions in high-energy collider experiments. We summarise new developments, essential features, and ongoing improvements within the Sherpa 3 release series. Phy... Read More about Event generation with Sherpa 3.

Tri-boson and WH production in the W + W + jj channel: predictions at full NLO accuracy and beyond (2024)
Journal Article
Denner, A., Pellen, M., Schönherr, M., & Schumann, S. (2024). Tri-boson and WH production in the W + W + jj channel: predictions at full NLO accuracy and beyond. Journal of High Energy Physics, 2024(8), Article 43. https://doi.org/10.1007/jhep08%282024%29043

In this work, we present the first full NLO predictions for the process pp → μ+νμe+νejj at the LHC in a typical tri-boson phase space. The NLO corrections reach 50% at the level of the fiducial cross section and have a very different hierarchy with r...

Polarised cross sections for vector boson production with S herpa (2024)
Journal Article
Hoppe, M., Schönherr, M., & Siegert, F. (2024). Polarised cross sections for vector boson production with S herpa. Journal of High Energy Physics, 2024(4), Article 1. https://doi.org/10.1007/jhep04%282024%29001

Measurements of vector boson polarisation in vector boson production processes offer a powerful probe of the electroweak symmetry breaking mechanism, scrutinising the Standard Model and new physics scenarios alike. Since massive vector bosons can onl... Read More about Polarised cross sections for vector boson production with S herpa.

Zero-bin subtraction and the q T spectrum beyond leading power (2024)
Journal Article
Ferrera, G., Ju, W., & Schönherr, M. (2024). Zero-bin subtraction and the q T spectrum beyond leading power. Journal of High Energy Physics, 2024(4), Article 5. https://doi.org/10.1007/jhep04%282024%29005

In this paper, we present an algorithm to construct the qT distribution at NLO accuracy to arbitrary power precision, including the assembly of suitable zero-bin subtrahends, in a mathematically well-defined way for a generic choice of rapidity-diver...
