The extraction of the strange quark parton distribution function (PDF) poses a long-standing puzzle. Measurements from neutrino-nucleus deep inelastic scattering (DIS) experiments suggest the strange quark is suppressed compared to the light sea quarks, while recent studies of W/Z boson production at the LHC imply a larger strange component at small x values. As the parton flavor determination in the proton depends on nuclear corrections, e.g. from heavy-target DIS, LHC heavy ion measurements… 
Impact of scale, nuclear PDF and temperature variations on the interpretation of medium-modified jet production data from the LHC
In this paper we present a study of in-medium jet modifications performed with JEWEL and PYTHIA 6.4, focusing on the uncertainties related to variations of the perturbative scales and nuclear parton

Vector boson production and neutrino deep-inelastic scattering (DIS) data are crucial for constraining the strange quark parton distribution function (PDF) and more generally for flavor decomposition
Compatibility of Neutrino DIS Data and Its Impact on Nuclear Parton Distribution Functions
In global analyses of nuclear parton distribution functions (nPDFs), neutrino deep-inelastic scattering (DIS) data have been argued to exhibit tensions with the data from charged-lepton DIS. Using

Constraining the nuclear gluon PDF with inclusive hadron production data
The nuclear parton distribution functions (nPDFs) of gluons are known to be difficult to determine with fits of deep inelastic scattering (DIS) and Drell-Yan (DY) data alone. Therefore, the nCTEQ15

The nuclear effects encoded in both most recent global fits of nuclear parton densities at next-to-leading order provide a good overall description of the LHC data, and a Bayesian-reweighting analysis for each particle data sample corroborates the existence of gluon antishadowing.
