Short-range correlations in nuclei
Or Hen, Holly Szumila-Vance, Lawrence Weinstein
Atomic nuclei are held together by the strong nuclear force acting between protons and neutrons (nucleons). While the long range, averaged part of this force is well described by t…
Long Range Outlook for Short-Range Correlations
Nadia Fomin, Or Hen, Julian Kahlbow +99
Short range correlated (SRC) N N pairs are pairs of nucleons with high relative momentum (prel > kF where kF ~ 250 MeV/c is the Fermi momentum in medium to heavy nuclei) and lower…
SIDIS Measurement with A=3 Nuclei
Zhihong Ye, Dipangkar Dutta, Dave Gaskell +5
We introduce a new experimental effort at Jefferson Lab (JLab) to precisely measure the ratios of charged pion electroproduction in Semi-Inclusive Deep Inelastic Scattering (SIDIS)…
Precision measurements of A=3 nuclei in Hall B
Or Hen, Dave Meekins, Dien Nguyen +55
We propose a high-statistics measurement of few body nuclear structure and short range correlations in quasi-elastic scattering at 6.6 GeV from H, He and H targets in H…
Comment on "Searching for flavor dependence in nuclear quark behavior"
O. Hen, F. Hauenstein, D. W. Higinbotham +6
Weinstein, et. al [1] [PRL 106, 052301 (2011)] and Hen, et. al [2] [PRC 85, 047301 (2012)] observed a correlation between the EMC effect and the amount of short range correlated (S…
Workshop on High-Intensity Photon Sources (HIPS2017) Mini-Proceedings
S. Ali, L. Allison, M. Amaryan +39
This workshop aimed at producing an optimized photon source concept with potential increase of scientific output at Jefferson Lab, and at refining the science for hadron physics ex…
Analysis of Neutron Stars Observations Using a Correlated Fermi Gas Model
O. Hen, A. W. Steiner, E. Piasetzky +1
Background: The nuclear symmetry energy is a fundamental ingredient in determining the equation of state (EOS) of neutron stars (NS). Recent terrestrial experiments constrain both…
Electroexcitation of the at low momentum transfer
A. Blomberg, D. Anez, N. Sparveris +92
We report on new p measurements at the resonance at the low momentum transfer region. The mesonic cloud dynamics is predicted to be dominant an…
Proton and Neutron Momentum Distributions in A = 3 Asymmetric Nuclei
O. Hen, L. B. Weinstein, S. Gilad +1
A proposal approved by the Jefferson Lab (JLab) PAC to study the proton-to-neutron momentum distribution ratio in A=3 nuclei via (e,e'p) scattering off 3He and 3H mirror nuclei. Th…
In Medium Nucleon Structure Functions, SRC, and the EMC effect
O. Hen, L. B. Weinstein, S. Gilad +1
A proposal approved by the Jefferson Lab PAC to study semi-inclusive deep inelastic scattering (DIS) off the deuteron, tagged with high momentum recoiling protons or neutrons emitt…
Comment on "Measurement of 2- and 3-nucleon short range correlation probabilities in nuclei"
Douglas W. Higinbotham, Or Hen
"Measurement of 2- and 3-nucleon short range correlation probabilities in nuclei" claimed to observe plateaus in the inclusive A/3He (e,e') ratios in the xB > 2 region; yet, a subs…
Symmetry Energy of Nucleonic Matter With Tensor Correlations
Or Hen, Bao-An Li, Wen-Jun Guo +2
The nuclear symmetry energy (E_sym(\roh)) is a vital ingredient of our understanding of many processes, from heavy-ion collisions to neutron stars structure. While the total nuclea…
Probing the Repulsive Core of the Nucleon-Nucleon Interaction via the 4He(e,e'pN) Triple-Coincidence Reaction
I. Korover N. Muangma, O. Hen, R. Shneor +115
We studied simultaneously the 4He(e,e'p), 4He(e,e'pp), and 4He(e,e'pn) reactions at Q^2=2 [GeV/c]2 and x_B>1, for a (e,e'p) missing-momentum range of 400 to 830 MeV/c. The knocked-…
Measurement of transparency ratios for protons from short-range correlated pairs
O. Hen, H. Hakobyan, R. Shneor +5
Nuclear transparency, Tp(A), is a measure of the average probability for a struck proton to escape the nucleus without significant re-interaction. Previously, nuclear transparencie…
Disentangling the EMC Effect
E. Piasetzky, O. Hen, L. B. Weinstein
The deep inelastic scattering cross section for scattering from bound nucleons differs from that of free nucleons.This phenomena, first discovered 30 years ago, is known as the EMC…

O. Hen, E. Piasetzky, L. B. Weinstein
Recently published measurements of the two nucleon short range correlation (-SRC) scaling factors, , strengthen the previously observed correlation between the magnit…
