Fragmentation Functions of light charged hadrons

  • Event time: 2:00pm
  • Event date: 8th November 2017
  • Speaker: Emanuele Roberto Nocera (Formerly School of Physics & Astronomy, University of Edinburgh)
  • Location: Higgs Centre Seminar Room, Room 4305,

Event details

I discuss the determination of the fragmentation functions (FFs) of light charged hadrons from a wide set of single-inclusive electron-positron annihilation cross section measurements. Specifically, I focus on the recent effort made by the NNPDF collaboration, using a methodology based on Monte Carlo sampling of  experimental uncertainties and Neural Networks for parton parametrisation. I discuss the quality of the NNPDF determination, including its stability upon inclusion of higher-order corrections, and some of its implications in the investigation of the spin structure of the nucleon and in the description of the hadron spectra measured at the LHC.
