The PYTHIA Facility

Christian Bierlich, Leif Lönnblad, Torbjörn Sjöstrand

The development and operation of large-scale particle physics facilities rely not only on accelerators and detectors, but also on sustained, high-precision simulation infrastructur…

HDSense: An efficient method for ranking observable sensitivity

Benoît Assi, Christian Bierlich, Rikab Gambhir +6

Identifying which observables most effectively constrain model parameters can be computationally prohibitive when considering full likelihoods of many correlated observables. This…

Iterative HOMER with uncertainties

Anja Butter, Ayodele Ore, Sofia Palacios Schweitzer +10

We present iHOMER, an iterative version of the HOMER method to extract Lund fragmentation functions from experimental data. Through iterations, we address the information gap betwe…

Characterizing the hadronization of parton showers using the HOMER method

Benoit Assi, Christian Bierlich, Philip Ilten +6

We update the HOMER method, a technique to solve a restricted version of the inverse problem of hadronization -- extracting the Lund string fragmentation function from data…

Simplifying Strangeness Fluctuations through Balance Functions in Proton-Proton Collisions

Christian Bierlich, Peter Christiansen

Recent measurements of event-by-event fluctuations of multistrange baryons and kaons in proton-proton collisions by ALICE have been proposed as sensitive probes to distinguish betw…

Describing Hadronization via Histories and Observables for Monte-Carlo Event Reweighting

Christian Bierlich, Phil Ilten, Tony Menzo +5

We introduce a novel method for extracting a fragmentation model directly from experimental data without requiring an explicit parametric form, called Histories and Observables for…
