  Multifractal analysis was performed on $pp$ collision data at $\sqrt{s}=$
0.9, 7 and 8 TeV from the CMS experiment at CERN. The data was obtained and
processed from the CERN Open Data Portal. Vertical analysis was used to compute
the generalised dimensions $D_q$ and the multifractal spectra $f(\alpha)$ of
the data, which reveals the level of complexity of its pseudorapidity
distribution. It was found that the $f(\alpha)$ curves widen with increasing
collision energy, signalling an increase in branching complexity.
