Summary of the research done in Pythia8/Anagntyr as an MCnetITN3 PhD student.

The first project was to develop a string "shoving" model to describe collective effects in heavy-ion collisions in terms of string interactions within the Lund model. This is done by constructing the Lorentz transformation to a symmetric frame where two string pieces are in parallel planes to calculate the resulting pairwise force due to the space-time overlap. Considering all such pairs of string pieces in a collision, the resulting total momentum change on a string piece is calculated. There is ongoing work to implement this along with the rope hadronization model in PYTHIA8.

The model is now further expanded using rope hadronization in heavy-ion collisions. Analysis involving the effects of string interactions on jets, known as jet quenching and the production yields of different hadron species in leading jets is also to be discussed.
