Abstract EN
We have studied the multifractality of pion emission process in 16O-AgBr interactions at 2.1 AGeV and 60 AGeV, 12C-AgBr and 24Mg-AgBr interactions at 4.5 AGeV, and 32S-AgBr interactions at 200 AGeV using Multifractal Detrended Fluctuation Analysis (MFDFA) method which is capable of extracting the actual multifractal property filtering out the average trend of fluctuation.
The analysis reveals that the pseudorapidity distribution of the shower particles is multifractal in nature for all the interactions; that is, pion production mechanism has inbuilt multiscale self-similarity property.
We have employed MFDFA method for randomly generated events for 32S-AgBr interactions at 200 AGeV.
Comparison of expt.
results with those obtained from randomly generated data set reveals that the source of multifractality in our data is the presence of long range correlation.
Comparing the results obtained from different interactions, it may be concluded that strength of multifractality decreases with projectile mass for the same projectile energy and for a particular projectile it increases with energy.
The values of ordinary Hurst exponent suggest that there is long range correlation present in our data for all the interactions.
