The impact of inclusive electron ion collider data on the strong coupling determination in a global PDF fit
L. A. Harland-Lang, T. Cridge, P. Newman +2
We present a study of the impact of data from the upcoming Electron Ion Collider (EIC) on the determination of the strong coupling within the context of the global MSHT fitting fra…
MSHT Approximate N3LO PDFs: Updates and Consequences for Phenomenology
T. Cridge, L. A. Harland-Lang, R. S. Thorne
We present updates to the MSHT approximate N3LO PDFs focusing upon recent developments, examining the impacts of newly determined splitting function and transition matrix element c…
A reassessment of the role of high data on the MSHT global PDF fit
L. A. Harland-Lang, T. Cridge, M. Reader +1
We present updates within the MSHT global PDF fit that focus on the high region, and on improving our understanding of the interplay of various theoretical contributions and ex…
A Stress Test of Global PDF Fits: Closure Testing the MSHT PDFs and a First Direct Comparison to the Neural Net Approach
L. A. Harland-Lang, T. Cridge, R. S. Thorne
We present a first global closure test of the fixed parameterisation (MSHT) approach to PDF fitting. We find that the default MSHT20 parameterisation can reproduce the features of…
