Novel theoretical tools in jet quenching
Isaksen, Johannes Hamre (Doctoral thesis, 2023-06-13)Jet quenching er studiet av hvordan egenskapene til en QCD-jet endrer seg når den passerer gjennom varmt nukleært materiale. Dette er relevant for kollisjoner av tunge ioner ved LHC og RHIC, da slike kollisjoner produserer ... -
Precise description of medium-induced emissions
Isaksen, Johannes Hamre; Tywoniuk, Konrad (Journal article; Peer reviewed, 2023)We study jet fragmentation via final-state parton splittings in the medium. These processes are usually calculated theoretically by invoking the large-Nc limit. In this paper we perform the first computation of a 1 → 2 ... -
A unified picture of medium-induced radiation
Isaksen, Johannes Hamre; Takacs, Adam; Tywoniuk, Konrad (Journal article; Peer reviewed, 2023)We revisit the picture of jets propagating in the quark-gluon plasma. In addition to vacuum radiation, partons scatter on the medium constituents resulting in induced emissions. Analytical approaches to including these ... -
Wilson line correlators beyond the large-Nc
Isaksen, Johannes Hamre; Tywoniuk, Konrad (Journal article; Peer reviewed, 2021)We study hard 1 → 2 final-state parton splittings in the medium, and put special emphasis on calculating the Wilson line correlators that appear in these calculations. As partons go through the medium their color continuously ...
