This meeting of the PDF4LHC is a working meeting towards a new PDF4LHC combination. Agenda is currently provisional.
Points for discussion from Joey.
-
Compare aN3LO PDFs, PDF luminosities among CT25, MSHT (new aN3LO PDF coming with updated input), NNPDF
-
Compare NNLO->aN3LO ratios. Ratio of ratio plot which indicates how much of the difference between PDFs is due to the different data sets/treatments in each PDF set, and howmuch is due to the transition to aN3LO
-
If differences still exist above the level we are comfortable with, come up with a framework to understand the origin of those differences, for example starting with a simpler data set
-
Impact of QED corrections; is there a way of further reducing the spread
-
Combination of the 3 PDFs for LHC phenomenology
