The inclusion of theory errors in PDF fits / A. Barontini. - In: NUCLEAR AND PARTICLE PHYSICS PROCEEDINGS. - ISSN 2405-6014. - (2023 Nov), pp. 1-6. [Epub ahead of print] [10.1016/j.nuclphysbps.2023.11.002]
Abstract:
We present ongoing work towards incorporating the missing higher-order uncertainty (MHOU) determined
through scale variations in the assessment of parton distribution functions (PDFs). Our PDFs fitting employs
the NNPDF4.0 methodology and our theory covariance matrix framework to account for theory errors. This
approach relies on the integration of MHOUs and their correlations via a theory covariance matrix. We validate
our estimation and assess the impact of theory errors on the PDFs and on LHC phenomenology.
