  Recent modelling of solar energetic particles (SEPs) propagation through the
heliospheric turbulence, also discussed in this workshop, has investigated the
role of the pitch-angle scattering and the perpendicular transport in spreading
particles in heliolongitude, as shown by multi-spacecraft measurements (STEREO
A/B, ACE, SOHO, etc.) at 1 AU in various energy ranges. In some events the
first-order pitch-angle anisotropy of the particles distribution is
not-negligible. We calculate the average perpendicular displacement due to the
gradient/curvature drift in an inhomogeneous turbulence accounting for
pitch-angle dependence for two MHD turbulence models: (a) 3-D isotropic, (b)
anisotropic as conjectured by Goldreich-Sridhar. We find in both cases that the
drift scales as $(1-\mu^2)^2$ with the cosine of pitch-angle $\mu$, in contrast
with previous models for transport of SEPs. This result can impact the models
of propagation of SEPs through the heliosphere.
