Determination of proton PDF uncertainties with Markov chain Monte Carlo
Peter Risse, Nasim Derakhshanian, Tomas Jezo +2
We present an analysis of parton distribution functions (PDFs) of the proton using Markov Chain Monte Carlo (MCMC) methods. The MCMC approach naturally implements Bayes' theorem an…

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…

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…
