Mechanisms of spin-flavor SU(6) symmetry breaking in quantum chromodynamics (QCD) are studied via an extraction of the free neutron structure function from a global analysis of deep inelastic scattering (DIS) data on the proton and on nuclei from A=2 (deuterium) to 208 (lead). Modification of the structure function of nucleons bound in atomic nuclei (known as the EMC effect) are consistently accounted for within the framework of a universal modification of nucleons in short-range correlated… 
From Quarks to Nuclei: Short Range Correlations Studies Across the Globe
Atomic nuclei are made of strongly interacting protons and neutrons (nucleons), which are themselves made of quarks and gluons (partons). One of the overarching goals of modern nuclear physics
Many-body factorization and position–momentum equivalence of nuclear short-range correlations
Ab-initio Quantum Monte Carlo (QMC) calculations of nuclei from deuterium to 40Ca, obtained using four different phenomenological and local chiral nuclear potentials, are analyzed using the
Regarding the Distribution of Glue in the Pion
Understanding why the scale of emergent hadron mass is obvious in the proton but hidden in the pion may rest on mapping the distribution functions (DFs) of all partons within the pion and comparing

Charm jets as a probe for strangeness at the future Electron-Ion Collider
We explore the feasibility of the measurement of charm-jet cross sections in charged-current deep-inelastic scattering at the future Electron-Ion Collider. This channel provides clean sensitivity to

Nucleon elastic form factors at accessible large spacelike momenta
A Poincar\'e-covariant quark+diquark Faddeev equation is used to compute nucleon elastic form factors on $0\leq Q^2\leq 18 \,m_N^2$ ($m_N$ is the nucleon mass) and elucidate their role as probes of
Selected Science Opportunities for the EicC
An electron ion collider has been proposed in China (EicC). It is anticipated that the facility would provide polarised electrons, protons and ion beams, in collisions with large centre-of-mass

Neutron structure function and inclusive deep inelastic scattering from3Hand3Heat large Bjorkenx
A detailed study of inclusive deep inelastic scattering (DIS) from mirror A = 3 nuclei at large values of the Bjorken variable x is presented. The main purpose is to estimate the theoretical
Constraints on the large-x d/u ratio from electron-nucleus scattering at x>1
Recently the ratio of neutron to proton structure functions F{sub 2}{sup n}/F{sub 2}{sup p} was extracted from a phenomenological correlation between the strength of the nuclear EMC effect and

TLDR
The results support the high-resolution description of high-momentum states being predominantly due to nucleons in SRC pairs, and compare to theoretical generalized contact formalism cross-section calculations show good agreement using both phenomenological and chiral nucleon-nucleon potentials.

How well do we know the neutron structure function?
TLDR
Correctly accounting for the Q(2) dependence of the data and calculations and restricting the nuclear corrections to microscopic models of the deuteron, the authors find a significantly smaller uncertainty in the extracted F(2n)/F(2p) ratio than in previous analyses.

Hadrons in the nuclear medium
Quantum chromodynamics (QCD), the microscopic theory of strong interactions, has not yet been applied to the calculation of nuclear wavefunctions. However, it certainly provokes a number of specific

TLDR
Simultaneous high-precision measurements of the EMC effect and short-range correlated abundances for several nuclei reveal a universal modification of the structure of nucleons in short- range correlated neutron–proton pairs.
