Abstract: The solar wind is a natural laboratory for investigating the emergence of turbulence in space plasmas. One of the main characters of the observed turbulence is the occurrence of intermittency in the inertial range, where the dynamics of the plans can be described in the framework of the magnetohydrodynamic model. One of the fingerprints of intermittency is the emergence of anomalous scaling features and multifractality for the fluctuations of both magnetic and velocity field. Here, using data from Solar Orbiter, we study the multifractal character of the Elsasser variables showing the different intermittent degree of z± fluctuations. Furthermore, we explore the correlation between the singularity spectra of z± fluctuations by studying the joint-multi fractal spectrum. A discussion of the role of stochastic energy redistribution along the inertial cascade is also presented in connection with the asymmetry of the observed singularity spectra.
