Determination of Nuclear PDFs using Markov Chain Monte Carlo Methods
N. Derakhshanian, P. Risse, T. Jezo +3
Global QCD analyses of nuclear parton distribution functions (nPDFs) have traditionally relied on the Hessian method for uncertainty estimation. However, the inherent Gaussian appr…
NLO heavy-quark contributions to DIS structure functions in the ACOT scheme
Edoardo Spezzano, Tomas Jezo, Michael Klasen +2
We present next-to-leading-order (NLO) calculations of heavy-quark contributions to deep-inelastic scattering (DIS) structure functions and within the Aivazis--Collins-…
Modification of Quark-Gluon Distributions in Nuclei by Correlated Nucleon Pairs
nCTEQ Collaboration, A. W. Denniston, T. Jezo +15
We extend the QCD Parton Model analysis using a factorized nuclear structure model incorporating individual nucleons and pairs of correlated nucleons. Our analysis of high-energy d…
Fast evaluation of heavy-quark contributions to DIS in APFEL++
P. Risse, V. Bertone, T. Ježo +4
Mass-dependent quark contributions are of great importance to DIS processes. The simplified-ACOT-scheme includes these effects over a wide range of momentum transfers up to next-to…
Towards a New nCTEQ global nPDF release
P. Risse, N. Derakhshanian, P. Duwentäster +11
We discuss the foundation for a new global nCTEQ nuclear PDF analysis, combining a number of our previous analyses into one consistent framework with updates to the underlying theo…
