CT25: Progress toward next-generation PDFs for precision phenomenology at the LHC
A. Ablat, A. Courtoy, S. Dulat +10
We summarize recent progress toward the next generation of CTEQ-TEA parton distribution functions, CT25, based on a global NNLO analysis that incorporates a significant sample of n…
Strong Coupling Constant Determination from the new CTEQ-TEA Global QCD Analysis
Alim Ablat, Sayipjamal Dulat, Marco Guzzi +5
We present a new determination of the strong coupling constant from a global QCD analysis CT25 of parton distribution functions (PDFs) that incorporates high-precision experi…
Improved Hessian Method in Global Analysis of Parton Distribution Functions
Wenxiao Zhan, Siqi Yang, Minghui Liu +3
The Hessian method is widely applied in the global analysis of parton distribution functions (PDFs), which uses a set of orthogonal eigenvectors to give predictions of a physical o…
Implications of CTEQ global analysis for collider observables
P. M. Nadolsky, H. -L. Lai, Q. -H. Cao +5
The latest CTEQ6.6 parton distributions, obtained by global analysis of hard scattering data in the framework of general-mass perturbative QCD, are employed to study theoretical pr…
