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…
Near Threshold Neutral Pion Electroproduction at High Momentum Transfers and Generalized Form Factors
P. Khetarpal, P. Stoler, I. G. Aznauryan +157
We report the measurement of near threshold neutral pion electroproduction cross sections and the extraction of the associated structure functions on the proton in the kinematic ra…
Accurate Test of Chiral Dynamics in the \boldmath Reaction
D. Hornidge, P. Aguar Bartolome, J. R. M. Annand +64
A precision measurement of the differential cross sections and the linearly polarized photon asymmetry $Σ\equiv (dσ_\perp - dσ_\parallel) \slash (dσ_\perp + dσ_\parallel)$…
Determination of the η mass with the Crystal Ball at MAMI-B
A. Nikolaev, P. Aguar-Bartolomé, J. Ahrens +59
A new precise determination of the η meson mass is presented. It is based on a measurement of the threshold for the γp -> pη reaction using the tagger focal-plane microscope detect…
Photoproduction of pi0pi0 and pi0pi+-pairs off the proton from threshold to the second resonance region
F. Zehr, B. Krusche, P. Aguar +59
Precise total cross-sections and invariant-mass distributions have been measured for photoproduction of pion pairs off the proton producing and final states fro…
Deep exclusive electroproduction off the proton at CLAS
K. Park, M. Guidal, R. W. Gothe +153
The exclusive electroproduction of above the resonance region was studied using the Large Acceptance Spectrometer () at Jefferson Laboratory by scatte…
Study of the gamma p --> pi0 pi0 p reaction with the Crystal Ball/TAPS at the Mainz
V. L. Kashevarov, A. Fix, S. Prakhov +68
The gamma p --> pi0 pi0 p reaction has been measured from threshold to 1.4 GeV using the Crystal Ball and TAPS photon spectrometers together with the photon tagging facility at the…
Measurement of the generalized form factors near threshold via at high
Kijun Park, Ralf Gothe, Krishna Adhikari +144
We report the first extraction of the pion-nucleon multipoles near the production threshold for the channel at relatively high momentum transfer ( up to 4.2 $\rm{GeV^2}…
A comparison of forward and backward pp pair knockout in 3He(e,e'pp)n
H. Baghdasaryan, L. B. Weinstein, J. M. Laget +1
Measuring nucleon-nucleon Short Range Correlations (SRC) has been a goal of the nuclear physics community for many years. They are an important part of the nuclear wavefunction, ac…
Coherent photoproduction of eta-mesons off 3He - search for eta-mesic nuclei
F. Pheron, J. Ahrens, J. R. M. Annand +71
Coherent photoproduction of -mesons off He, i.e. the reaction , has been investigated in the near-threshold region. The experiment was performed…
Evidence for the Onset of Color Transparency in Electroproduction off Nuclei
L. El Fassi, L. Zana, K. Hafidi +154
We have measured the nuclear transparency of the incoherent diffractive process in C and Fe targets relative to H using a 5 GeV electron beam. The nu…
