SUMMARY:Proton structure in the precision LHC era - Cameron Voisey (Cambri
 dge)
DTSTART:20191024T150000Z
DTEND:20191024T160000Z
UID:TALK131272@talks.cam.ac.uk
CONTACT:Mathieu Pellen
DESCRIPTION:A significant limitation in current determinations of Parton D
 istribution Functions (PDFs)\, which describe the structure of protons\, i
 s that the impact of theoretical uncertainties is not systematically accou
 nted for. I will present two frameworks for the inclusion of additional so
 urces of theoretical uncertainty in PDF fits\, and present the first studi
 es of the effects of missing higher-order uncertainties\, which are estima
 ted using scale variations\, on PDFs in the context of the NNPDF approach.
