Particle multiplicity distributions in silicon-emulsion collisions at4.5AGeV/c

Unified description of multiplicity distributions of final-state particles produced in collisions at high energies

“…In our previous work [24,25] on multiplicity and transverse energy distributions of produced particles in Au-Au and Pb-Pb collisions at high energies, the calculated method is also includable in the framework of the present model. The number of participant nucleons at a fixed impact parameter is regarded as m j .…”

Multiplicity fluctuations of target residues in forward and backward hemispheres in12C–AgBr interactions at 4.5AGeV

“…The 4.5 A GeV energy is called the Dubna energy. According to Liu et al [27], in the study of nuclear fragmentation, the Dubna energy region is more important than the SPS energy region because the nuclear limiting fragmentation may set in at the Dubna energy. Here lies the importance of this work.…”

Parity violation in nuclear systems

“…This emphasis is largely motivated by both the feasibility of the corresponding experiments in a near future (see Stiliaris's talk at this conference) and a safer interpretability of possible effects. These ones include the photon-emission asymmetry in the thermal-energy radiative capture of polarized neutrons by protons, n + p → d + γ [13,14,15,16], presently performed at LANSCE, the asymmetry in the deuteron photo-disintegration depending on the photon helicity [17,18,19,20], which could be performed at JLab, IASA, SPring-8, · · ·, the deuteron anapole moment [21,22,23,24], the pnc deuteron electro-disintegration in relation with the SAMPLE experiment [25,16], and the longitudinal asymmetry and the neutron-spin rotation in np scattering [20]. Some earlier works could be quoted.…”

“…Some earlier works could be quoted. The recent ones involve new methods (effective-field theories [13,15]), improved N N interaction models (AV18+ · · · [15,24,16,18,20]), more complete calculations (two-body currents [25,16]), and increased attention to gauge invariance [23,24,20]. A few remarks are made below about these different works.…”

“…In pnc-electron experiments performed on the deuteron, aiming at determining the contribution of strange quarks to nucleon form factors, there was some concern about the role of a nuclear pnc effect. This one was studied in two different works [25,16] which showed that the effect, a few percents, would be negligible. Actually, the main role of pnc nuclear effects in this process (together with that one involving the proton) is an indirect one.…”
