The MSHT20 PDFs represented a significant step forward in terms of the accuracy and precision of the resulting PDFs, and followed substantial progress on the experimental, methodological and theoretical fronts. I will review the MSHT20 PDFs before detailing several of the subsequent studies we have undertaken within the MSHT collaboration, both completed and ongoing work. This will range from...
In the past year, several new achievements have been obtained by the NNPDF
collaboration: the release of the 4.0 PDF set, the publication of the fitting
code, the PDF4LHC20 combination, and a dedicated study on the intrinsic charm
content of the proton.
I will review these progresses, and present the topics that are currently being
investigated, to outline the future directions of...
We present fits to determine parton distribution functions (PDFs) using a diverse set of measurements from the ATLAS experiment at the LHC, including inclusive W and Z boson production, ttbar production, W+jets and Z+jets production, inclusive jet production and direct photon production. These ATLAS measurements are used in combination with deep-inelastic scattering data from HERA. Particular...
