Structure functions and Parton Densities
Talk in Parallel Session at DIS2013
The theoretical foundations of the quantum statistical approach to parton distributions are reviewed together with the phenomenological motivations from a few specific features of Deep Inelastic Scattering data. The chiral properties of QCD lead to strong relations between quarks and antiquarks distributions and automatically account for the flavor and helicity symmetry breaking of the sea. We...

Structure functions and Parton Densities
Talk in Parallel Session at DIS2013
In this talk, we discuss the compatibility of different deeply
inelastic neutrino-nucleus data sets and the universal nuclear
parton distribution functions (PDFs). This is an issue that has
lately been investigated by different groups but the conclusions
have been contradictory. While some studies have found a good overall
agreement between the nuclear PDFs and the neutrino data,...

Structure functions and Parton Densities
Talk in Parallel Session at DIS2013
A global analysis of the proton PDF requires a combination of DIS, DY,
and jet data. The flavor differentiation depends heavily on the DIS
data, much of which is measured on nuclear targets; hence the nuclear
PDFs (nPDFs) come into play. A global nPDF analysis finds tensions
between the nuclear correction factors in various data sets. We
explore possible sources of this tension, and...

Structure functions and Parton Densities
Talk in Parallel Session at DIS2013
A description of a nucleon structure in terms of partons demands
knowledge of parton momentum-, helicity- and transversity
distribution functions. COMPASS facility at CERN, with its high energy,
polarised muon beam, large polarised proton- and deuteron targets
and particle identification detectors, permits investigating the
(longitudinal and transverse) spin-dependent structure...

Future experiments
Talk in Parallel Session at DIS2013
I will present the current status of the nuclear parton distribution
functions highlighting the diverse possibilities that would be opened
by the LHeC.
