Measuring hadronic Higgs boson branching ratios at future lepton colliders (2024)
Journal Article
Knobbe, M., Krauss, F., Reichelt, D., & Schumann, S. (2024). Measuring hadronic Higgs boson branching ratios at future lepton colliders. The European Physical Journal C, 84(1), Article 83. https://doi.org/10.1140/epjc/s10052-024-12430-4

We present a novel strategy for the simultaneous measurement of Higgs-boson branching ratios into gluons and light quarks at a future lepton collider operating in the Higgs-factory mode. Our method is based on template fits to global event-shape obse... Read More about Measuring hadronic Higgs boson branching ratios at future lepton colliders.

A new approach to color-coherent parton evolution (2023)
Journal Article
Herren, F., Höche, S., Krauss, F., Reichelt, D., & Schönherr, M. (2023). A new approach to color-coherent parton evolution. Journal of High Energy Physics, 2023(10), Article 91. https://doi.org/10.1007/jhep10%282023%29091

We present a simple parton-shower model that replaces the explicit angular ordering of the coherent branching formalism with a differentially accurate simulation of soft-gluon radiation by means of a non-trivial dependence of the splitting functions...

(N)NLO+NLL’ accurate predictions for plain and groomed 1-jettiness in neutral current DIS (2023)
Journal Article
Knobbe, M., Reichelt, D., & Schumann, S. (2023). (N)NLO+NLL’ accurate predictions for plain and groomed 1-jettiness in neutral current DIS. Journal of High Energy Physics, 2023(9), Article 194. https://doi.org/10.1007/jhep09%282023%29194

The possibility to reanalyse data taken by the HERA experiments offers the chance to study modern QCD jet and event-shape observables in deep-inelastic scattering. To address this, we compute resummed and matched predictions for the 1-jettiness distr... Read More about (N)NLO+NLL’ accurate predictions for plain and groomed 1-jettiness in neutral current DIS.

Practical jet flavour through NNLO (2022)
Journal Article
Caletti, S., Larkoski, A. J., Marzani, S., & Reichelt, D. (2022). Practical jet flavour through NNLO. The European Physical Journal C, 82(7), Article 632. https://doi.org/10.1140/epjc/s10052-022-10568-7

An infrared and collinear (IRC) safe definition of the partonic flavour of a jet is vital for precision predictions of quantum chromodynamics at colliders. Jet flavour definitions have been presented in the literature, but they are typically defined... Read More about Practical jet flavour through NNLO.

A Fragmentation Approach to Jet Flavor (2022)
Journal Article
Caletti, S., Larkoski, A. J., Marzani, S., & Reichelt, D. (2022). A Fragmentation Approach to Jet Flavor. Journal of High Energy Physics, 2022(10), Article 158. https://doi.org/10.1007/jhep10%282022%29158

An intuitive definition of the partonic flavor of a jet in quantum chromodynamics is often only well-defined in the deep ultraviolet, where the strong force becomes a free theory and a jet consists of a single parton. However, measurements are perfor... Read More about A Fragmentation Approach to Jet Flavor.

Phenomenology of jet angularities at the LHC (2022)
Journal Article
Reichelt, D., Caletti, S., Fedkevych, O., Marzani, S., Schumann, S., & Soyez, G. (2022). Phenomenology of jet angularities at the LHC. Journal of High Energy Physics, 2022(3), Article 131. https://doi.org/10.1007/jhep03%282022%29131

We compute resummed and matched predictions for jet angularities in hadronic dijet and Z+jet events with and without grooming the candidate jets using the SoftDrop technique. Our theoretical predictions also account for non-perturbative corrections f... Read More about Phenomenology of jet angularities at the LHC.

Improving the simulation of quark and gluon jets with Herwig 7 (2017)
Journal Article
Reichelt, D., Richardson, P., & Siodmok, A. (2017). Improving the simulation of quark and gluon jets with Herwig 7. The European Physical Journal C, 77(12), Article 876. https://doi.org/10.1140/epjc/s10052-017-5374-8

The properties of quark and gluon jets, and the differences between them, are increasingly important at the LHC. However, Monte Carlo event generators are normally tuned to data from e+e−e+e− collisions which are primarily sensitive to quark-initiate...

Colour Reconnections in Quark and Gluon Jets in Herwig 7 (2017)
Journal Article
Reichelt, D., Richardson, P., & Siódmok, A. (2017). Colour Reconnections in Quark and Gluon Jets in Herwig 7. Acta Physica Polonica B, 48(6), 1167-1173. https://doi.org/10.5506/aphyspolb.48.1167

Major event generators deviate significantly in their description of quark and gluon initiated jets. The modelling of these is particularly sensitive to the colour reconnection model used in the cluster hadronization model in the event generator Herw...
