A technique has been recently proposed to address the main limitations of past neutrino scattering experiments. In particular, it allows precise measurements of high statistics samples of (anti)neutrino-hydrogen interactions together with various nuclear targets. The planned high intensity LBNF beams give access to a broad mixture of measurements of electroweak parameters, QCD and hadron...
We present a new determination of nuclear Parton Distributions Functions (PDFs) from a number of new processes that constrain the nuclear gluons: single jet and dijet cross-sections from ATLAS and CMS, direct photon production from ATLAS, and charm production by LHC. We use NNLO perturbative QCD calculations for all processes included in the fit. The proton baseline, which nNNPDF3.0 reduces to...
As we strive for higher precision QCD predictions, a detailed knowledge of the nuclear PDFs is critical. The nCTEQ collaboration has recently examined LHC W/Z production data in heavy ion collisions, as well as JLab DIS data on a range of nuclear targets. Both these sets strongly influence the resulting nPDFs, and these advances are reflected in the recent nCTEQ PDF releases. This data...
The CJ15 global next-to-leading-order analysis of PDFs utilized, amongst others, inclusive and tagged DIS structure function data from Jefferson Lab (JLab) and high-precision charged lepton and W-boson asymmetry data from Fermilab. As an extension to the CJ15 analysis, new JLab Hall A and C data from experiments jl00106F2, e06009d, e99118, jlcee96 and e03103, and Hall B data from the BONuS and...
In the atomic nucleus there exist a strong nucleon-nucleon (NN) interaction at short distance. When a two-nucleon pair are separated by $r_{1,2} \leq 1.5$ fm, they will interact strongly and and the pair obtains large back-to-back relative momenta. The probability of these short distance interactions is enhanced by the tensor force in isospin=0 neutron-proton ($np$) pairs. Under certain...
