Jet Fragmentation at the LHC
… of non-perturbative functions called Generalized Fragmentation Functions (GFFs) as a step towards these goals. This theoretical framework enables the calculation of a broad set of semi-inclusive jet observables. We explore known observables whose distributions can now be calculated using GFFs, and …

Numerical Simulation of Corium Jet Fragmentation
… molten corium may fall in the form of a jet into a water pool. The fragmentation of the corium jet is a critical process concerning Fuel-Coolant Interactions (FCI). A steam explosion could occur depending on jet fragmentation and dispersion in the water. A 2-D in-house CFD MATLAB script …

Partonic rescatterings during jet fragmentation in the QCD vacuum
… in high energy collisions can emerge from the fragmentation and hadronization evolution of a partonic jet. We first describe an analysis procedure to search for these effects and define key observables. We demonstrate this procedure using Monte Carlo (MC) simulations which serve to establish a …

Detailed characterization of jets in heavy ion collisions using jet fragmentation functions
In this thesis the jet fragmentation function of inclusive jets with transverse momentum PT > 100 GeV/c in PbPb collisions is measured for reconstructed charged particles with PT > 1 GeV/c within the jet cone. A data sample of PbPb collisions collected in 2011 at a center-of-mass energy of [square …

Data-driven extraction of the substructure of quark and gluon jets in proton-proton and heavy-ion collisions
The modification of quark- and gluon-initiated jets in the quark-gluon plasma produced in heavy-ion collisions is a long-standing question that has not yet received a definitive answer from experiments. In particular, the size of the modifications differs between theoretical models. Therefore a …

Baryon-to-Meson Ratios in Jets from Au+Au and p+p Collisions at 200 GeV
… believed to be responsible for this enhancement. Jets have served as powerful probes of QGP properties, with numerous measurements revealing significant modifications to jet yields and internal structure. LHC measurements reveal that, despite observable medium effects on jet fragmentation, the …

TRANSVERSE MOMENTUM EVOLUTION OF HADRON-V0 CORRELATIONS IN PP COLLISIONS AT 7 TEV
… which allow the study of high-pT parton fragmentation without full jet reconstruction. We present the results of correlations between charged trigger particles and associated strange baryons and mesons. Enhancements of the azimuthal correlations are seen at dphi= 0 and dphi= pi, resulting …
