Open AccessOpen charm production cross section from combined LHC experiments in pp collisions at \(\sqrt{s} = 5.02\) TeV
Open charm production in proton–proton collisions represents an important tool to investigate some of the most fundamental aspects of quantum chromodynamics, from the partonic mechanisms of heavy-quark product...

Open AccessThe dynamic hadronization of charm quarks in heavy-ion collisions
The Pythia8/Angantyr model for heavy ion collisions was recently updated with a mechanism for global colour reconnection. The colour reconnection model used is QCD colour algebra inspired and enhances baryon pro...

Open AccessHyperfine splitting effects in string hadronization
We revisit the recipe for hadron formation in the Lund string hadronization model. Given an incoming quark or quark-diquark pair, weights for hadron formation are updated to take hyperfine splitting effects ar...

Open AccessHadronic rescattering in pA and AA collisions
In a recent article we presented a model for hadronic rescattering, and some results were shown for \(\mathrm {p}\mathrm {p}\) ...

Open AccessSetting the string shoving picture in a new frame
Based on the recent success of the Angantyr model in describing multiplicity distributions of the hadronic final state in high energy heavy ion collisions, we investigate how far one can go with a such a strin...

Open AccessConfronting experimental data with heavy-ion models: Rivet for heavy ions
The Rivet library is an important toolkit in particle physics, and serves as a repository for analysis data and code. It allows for comparisons between data and theoretical calculations of the final state of col...

Open AccessDipole evolution: perspectives for collectivity and γ*A collisions
The transverse, spatial structure of protons is an area revealing fundamental properties of matter, and provides key input for deeper understanding of emerging collective phenomena in high energy collisions of...

Open AccessThe Angantyr model for heavy-ion collisions in Pythia8
We present a new model for building up complete exclusive hadronic final states in high energy nucleus collisions. It is a direct extrapolation of high energy pp collisions (as described by Pythia), and thus brid...

Open AccessDiffractive and non-diffractive wounded nucleons and final states in pA collisions
We review the state-of-the-art of Glauber-inspired models for estimating the distribution of the number of participating nucleons in pA and AA collisions. We argue that there is room for improvement in these mode...

Open AccessEffects of overlap** strings in pp collisions
In models for hadron collisions based on string hadronization, the strings are usually treated as independent, allowing no interaction between the confined colour fields. In studies of nucleus collisions it ha...
