Fluctuation and fractality study of target residue in S 3 2 -AgBr interaction at 200 A GeV

Evidence of self-affine multiplicity fluctuation of target residues in 84 Kr-AgBr interactions at 1.7 AGeV

“…The cascade-evaporation model is based on the assumption that statistical equilibrium is established in the decaying system and its life time is assumed to be much longer than the time needed to redistribute its excitation energy among the different nucleons in the nucleus. However, different experimental data indicate the existence of a nonequilibrium process involved in the emission of black particles [5][6][7][8][9][10] .…”

“…According to Mandelbrot [15] , when a given pattern is differently scaled in different directions, it is called self-affine fractal. Up to now most of the intermittency investigations of target fragments have been performed based on the selfsimilar nature of the fluctuations [6][7][8][9][10][16][17][18][19][20][21] ; only a few works report on the evidence of self-affine multiparticle production indicated by the data [22][23][24][25][26][27][28][29][30][31] .…”

Target excitation dependence of degree of multifractality and critical exponent in ultrarelativistic nuclear collision

“…Some work [1][2][3][4][5][6][7][8] has been done with the help of knocked-out target protons, having medium energy (30-400 MeV). The knocked-out target protons are also supposed to carry some information about the interaction dynamics, since the time scale of emission of these particles is the same as that of the produced particles.…”

Multiplicity fluctuation analysis of target residues in nucleus-emulsion collisions at a few hundred MeV/nucleon

“…In high energy nucleus-nucleus collisions, target fragmentation also may carried out the information about colliding mechanism. The non-statistical fluctuations of the emission of target evaporated fragments in lepton-nucleus, hadron-nucleus and nucleus-nucleus collisions at high energies have been investigated not only in one-dimensional phase-space [2][3][4][5][6][7][8][9][10][11] but also in twodimensional phase-space [12][13][14][15][16][17][18][19][20][21]. The evidence of non-statistical fluctuation of target evaporated fragments is obtained in most of these investigation, but in some of these studies [2,4,21] the saturation effect is observed in the dependence of the power law growth of the SFM and decreasing phase-space interval size, these effects indicate that there is not a non-statistical fluctuation in the emission of target evaporated fragments.…”
