A Task Force on Strong Coupling Determinations from Event Shapes
Anthony Badea, Luca Buonocore, Gherardo Vita +19
The strong coupling constant is a fundamental parameter of the Standard Model. Its precise determination is essential for accurately predicting, studying, and understanding p…
A generalised- jet algorithm for Deep Inelastic Scattering
Melissa van Beekveld, Silvia Ferrario Ravasio, Alexander Karlberg +1
We introduce an inclusive generalised- jet algorithm for Deep Inelastic Scattering, defined in the Breit frame and implemented in fjcontrib. The family of algorithms is govern…
Logarithmically-accurate and positive-definite NLO shower matching
Melissa van Beekveld, Silvia Ferrario Ravasio, Jack Helliwell +6
We present methods to achieve NLL+NLO accurate parton showering for processes with two coloured legs: neutral- and charged-current Drell-Yan, and Higgs production in collision…
A new standard for the logarithmic accuracy of parton showers
Melissa van Beekveld, Mrinal Dasgupta, Basem Kamal El-Menoufi +9
We report on a major milestone in the construction of logarithmically accurate final-state parton showers, achieving next-to-next-to-leading-logarithmic (NNLL) accuracy for the wid…
Two-loop anomalous dimensions for small- jet versus hadronic fragmentation functions
Melissa van Beekveld, Mrinal Dasgupta, Basem Kamal El-Menoufi +3
We study the collinear fragmentation of highly energetic jets defined with a small jet radius. In particular, we investigate how the corresponding fragmentation functions differ fr…
Introduction to the PanScales framework, version 0.1
Melissa van Beekveld, Mrinal Dasgupta, Basem Kamal El-Menoufi +11
In this article, we document version 0.1 of the PanScales code for parton shower simulations. With the help of a few examples, we discuss basic usage of the code, including tests o…
