“…At intermediate energies, no sign of CT was observed in A(e, e p) measurements on a variety of nuclear targets and four-momentum transfers Q 2 8 (GeV/c) 2 [8][9][10][11][12][13][14]. The nuclear 12 C(p, 2p) transparencies were studied at Brookhaven National Laboratory (BNL) [15][16][17]. The transparency first shows a rise with increasing incoming proton momentum and drops for momenta larger than 9 GeV/c.…”

Background:The recent Jefferson Laboratory data for the nuclear transparency in ρ 0 electroproduction have the potential to settle the scale for the onset of color transparency (CT) in vector meson production. Purpose: To compare the data to calculations in a relativistic and quantum-mechanical Glauber model and to investigate whether they are in accordance with results including color transparency given that the computation of ρ-nucleus attenuations is subject to some uncertainties. Method: We compute the nuclear transparencies in a multiple-scattering Glauber model and account for effects stemming from color transparency, from ρ-meson decay, and from short-range correlations (SRC) in the final-state interactions (FSI). Results:The robustness of the model is tested by comparing the mass dependence and the hard-scale dependence of the A(e, e p) nuclear transparencies with the data. The hard-scale dependence of the (e, e ρ 0 ) nuclear transparencies for 12 C and 56 Fe are only moderately affected by SRC and by ρ 0 decay. Conclusions:The RMSGA calculations confirm the onset of CT at four-momentum transfers of a few (GeV/c) 2 in ρ meson electroproduction data. A more precise determination of the scale for the onset of CT is hampered by the lack of precise input in the FSI and ρ-meson decay calculations.

“…One can find various methods to define NT experimentally [1][2][3][4][5][6][7]. NT as the ratio of nuclear cross section of the reaction [1][2][3]; as some behavior of the average characteristics of secondary particles produced in hA and AA collisions as a function of the number of identified baryons [4][5][6]; as behavior of the nuclear modification factor (RAA) vs number of participants nucleons [7]. All the above definitions of NT are the same with a difference in the procedure of scaling / normalizing the data.…”

“…The increase in the NT indicates the appearance of CT as compared to the predictions of traditional nuclear physics expectations. A lot of efforts have been made to search for the CT effect, including A(p, 2p) [1,11,12,13,14] and A(e, e p) [15,16,17,18,19,20] reactions with protons as a probe for studying the effect. Mesons were used on the premise that at large Q 2 the values of r ⊥ are significantly smaller than the size of the nucleon.…”

The use of nuclear transparency effect of π − -mesons in proton, and deuteron induced interactions with carbon nuclei at 4.2A GeV /c, to get information about the properties of nuclear matter, is presented in this work. Half angle (θ 1/2 ) technique is used to extract information on nuclear transparency effect. The θ 1/2 divides the multiplicity of charged particles into two equal parts depending on their polar angle in the lab. frame in pp interactions. Particles with angle smaller than (incone particles) and greater than (outcone particles) θ 1/2 are considered separate.The average values of multiplicity, momentum and transverse momentum of the π −mesons are analyzed as a function of a number of identified protons in an event. We observed evidences in the data which could be considered as transparency effect. For quantitative analysis, the results are compared with cascade model. The observed effects are categorized into leading effect transparency and medium effect transparency. The transparency in the latter case could be the reason of collective interactions of grouped nucleons with the incident particles.Nuclear transparency effect of π − -mesons M. Ajaz et al.
