Energy exchange between (3+1)D colliding spatiotemporal solitons (STSs) in dispersive media with the cubic-quintic (CQ) nonlinearity is studied by numerical simulations using the split-step Fourier method in the paper.Extensive simulations reveal that energy exchange between two (3+1)D colliding STSs is sensitive to their phase difference.When the phase difference between two colliding STSs of equal and opposite velocities varies from 0 to π,the light bullet leading in phase gains energy.When the phase difference vahies from 0 to π,the one leading in phase loses energy.
