Impact of string interactions on the space-time evolution of hadronic vertices

  title={Impact of string interactions on the space-time evolution of hadronic vertices},
  author={Smita Chakraborty and Leif Lonnblad},
We investigate the space-time picture of string evolution and hadron production in a fully string-based model for high energy collisions involving heavy ions. We find that although the density strings is quite large at the time of hadronization in a central heavy ion collision, the initial overlap between them right after the collisions is not necessarily large. We also find that when including string–string interactions using the so-called shoving model, the density of strings is decreased…

Jet modifications from colour rope formation in dense systems of non-parallel strings

We revisit our rope model for string fragmentation that has been shown to give a reasonable description of strangeness and baryon enhancement in high-multiplicity pp events at the LHC. A key

A multiple-interaction model for the event structure in hadron collisions.

It is argued that hadronic events contain a varying number of semihard parton-parton interactions, with an average interaction rate given by perturbative QCD, and the variation between different events given by Poissonian statistics for each impact parameter separately.

The space–time structure of hadronization in the Lund model

The density of hadron production is quantified under different conditions and the (not unexpected) conclusion is that this density can become quite high, and thereby motivate the observed collective behaviour in high-multiplicity collisions.

Setting 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

The Angantyr model for heavy-ion collisions in Pythia8

A bstractWe 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

From Glasma to Quark Gluon Plasma in heavy ion collisions

When two sheets of color glass condensate collide in a high-energy heavy-ion collision, they form matter with very high energy densities called the glasma. We describe how this matter is formed, its
