Pion Fragmentation Functions at High Energy Colliders
read the original abstract
We revisit the description of pion production in proton-proton collisions in the light of the very precise data taken at the Large Hadron Collider (LHC) over the past decade. First attempts to include LHC results in next-to-leading order global QCD analyses of parton-to-pion fragmentation functions insinuated some conflict between data sets at different center-of-mass system energies. We show that the data can be well described within their uncertainties by a consistent set of pion fragmentation functions once the theoretical scale dependence is taken into account in the global QCD analysis.

Precise QCD Predictions for Hadron-in-jet Production in $e^+e^-$ Collisions
First NNLO QCD predictions for hadron-in-jet cross sections in e+e- two- and three-jet events, with ALEPH comparisons showing improved convergence when the fragmentation scale is set by the jet resolution.

Exploring nuclear modification using one-point energy correlator at the electron-ion collider
OPEC in e+A collisions factorizes in TMD QCD and predicts ~0.3–0.4 nuclear suppression at small angles, growing with angle, as a probe of cold-nuclear-matter broadening.

Phenomenological extraction of fragmentation functions in a $p\bar{p}$ environment
Kinematic cuts in Tevatron p-pbar photon-hadron production make cross-section ratios of kaons to pions approximate u-quark fragmentation-function ratios, enabling flavour-separated FF constraints.
