nCTEQ15 - Global analysis of nuclear parton distributions with uncertainties

Understand

We present the first official release of the nCTEQ nuclear parton distribution functions with errors.

• The main addition to the previous nCTEQ PDFs is the introduction of PDF uncertainties based on the Hessian method.
• Another important addition is the inclusion of pion production data from RHIC that give us a handle on constraining the gluon PDF.
• This contribution summarizes our results from arXiv:1509.00792 and concentrates on the comparison with other groups providing nuclear parton distributions.
