Parton distribution functions and strong coupling constant: MSHT
T. Cridge, L. A. Harland-Lang, M. Reader +1
We present an overview of the MSHT family of global PDF fits. We describe the underlying methodology, including parameterisation choice, theoretical inputs and datasets included in…
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…
Combination of aNLO PDFs and implications for Higgs production cross-sections at the LHC
Thomas Cridge, Lucian A. Harland-Lang, Jamie McGowan +14
We discuss how the two existing approximate NLO (aNLO) sets of parton distributions (PDFs) from the MSHT20 and NNPDF4.0 series can be combined for LHC phenomenology, both i…
Closure Testing the MSHT PDFs and a First Direct Comparison to the Neural Net Approach
L. A. Harland-Lang, R. S. Thorne, T. Cridge
We present a brief overview of the first global closure test of the fixed parameterisation (MSHT) approach to PDF fitting. We find that the default MSHT20 parameterisation can repr…
MSHT Updates 2024
R. S. Thorne, T. Cridge, L. Harland-Lang
We present various recent updates related to the MSHT20 PDF sets, and particularly to the MSHT20 approximate NLO (aNLO) PDFs. These include an investigation of including ei…
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…
A Benchmarking of QCD Evolution at Approximate
A. Cooper-Sarkar, T. Cridge, F. Giuli +6
We present a detailed benchmarking of different treatments of the QCD evolution of unpolarized PDFs at approximate () order in the QCD coupling. Namely, the impleme…
Les Houches 2023: Physics at TeV Colliders: Standard Model Working Group Report
J. Andersen, B. Assi, K. Asteriadis +81
This report presents a short summary of the activities of the "Standard Model" working group for the "Physics at TeV Colliders" workshop (Les Houches, France, 12-30 June, 2023).
A first determination of the strong coupling at approximate NLO order in a global PDF fit
T. Cridge, L. A. Harland-Lang, R. S. Thorne
We present the first determination of the value of the strong coupling via a simultaneous global fit of the proton parton distribution functions (PDFs) at approximate NLO (aN…

T. Cridge, L. A. Harland-Lang, R. S. Thorne
We present an analysis of two key sets of data constraining the high gluon at up to approximate NLO in QCD within the MSHT global PDF fitting framework. We begin with LHC…

We investigate the impact of the high precision ATLAS and CMS 7 TeV measurements of inclusive jet production on the MMHT global PDF analysis at next-to-next-to-leading order (NNLO)…
The effect on PDFs and due to changes in flavour scheme and higher twist contributions
R. S. Thorne
I consider the effect on MSTW partons distribution functions (PDFs) due to changes in the choices of theoretical procedure used in the fit. I first consider using the 3-flavour fix…
