Measurement of the α-particle monopole transition form factor challenges theory: a low-energy puzzle for nuclear forces?
S. Kegel, P. Achenbach, S. Bacca +30
We perform a systematic study of the -particle excitation from its ground state to the resonance. The so-called monopole transition form factor is investigated v…
The exotic meson with and its decay into
M. G. Alexeev, G. D. Alexeev, A. Amoroso +192
We study the spin-exotic amplitude in single-diffractive dissociation of 190 GeV pions into using a hydrogen target and confirm the $π_1(1600) \to…
Measurements of the electron-helicity asymmetry in the quasi-elastic process
Tim Kolar, Sebouh J. Paul, Patrick Achenbach +43
We present measurements of the electron helicity asymmetry in quasi-elastic proton knockout from H and C nuclei by polarized electrons. This asymmetry depends on the f…
Probing transversity by measuring polarisation in SIDIS
M. G. Alexeev, G. D. Alexeev, A. Amoroso +196
Based on the observation of sizeable target-transverse-spin asymmetries in single-hadron and hadron-pair production in Semi-Inclusive measurements of Deep Inelastic Scattering (SID…
Operation and characterization of a windowless gas jet target in high-intensity electron beams
B. S. Schlimme, S. Aulenbacher, P. Brand +54
A cryogenic supersonic gas jet target was developed for the MAGIX experiment at the high-intensity electron accelerator MESA. It will be operated as an internal, windowless target…
First observation of a nuclear -state of hypernucleus,
M. Yoshimoto, J. K. Ahn, B. Bassalleck +46
Bound-systems of -- are studied via capture at rest followed by emission of a twin single- hypernucleus in the emulsion detectors. Two events forming…
