AbstractUsing radial velocities of vibrationally excited H2 emission in OMC1 we present the structure functions and the scaling of the structure functions with their order at scales ranging from 70 AU to 30000 AU extending earlier related studies to scales lower by two orders of magnitude. The structure functions for OMC1 show clear deviations from power laws at 1500 AU. The scaling of the higher order structure functions with order deviates from predicted theoretical scalings. Observational results are compared with simulations of supersonic hydrodynamic turbulence. The unusual scaling is explained as a selection effect of preferentially observing the shocked part of the gas. The simulations are unable to reproduce the deviations from power laws of the structure functions.

Gluon Bremsstrahlung

Earlier work has shown that in processes involving structure functions and/or fragmentation functions initiated by 2 → 2 parton subprocesses there is a gauge invariant part that dominates higher order corrections, and for the gluon Bremsstrahlung contributions to this part simple and general expressions were derived and applied to [Formula: see text]. Here we apply these expressions and determine the dominant part of qg → γq, thus complementing the work and demonstrating the efficiency of the approach.

Gluon Bremsstrahlung

It is shown that in processes involving structure functions and/or fragmentation functions initiated by 2→2 parton subprocesses, there is a gauge invariant part that dominates higher order corrections over a sizeable kinematic domain. The gluon Bremsstrahlung contribution to this part arises from collinear and soft gluon configurations. This Bremsstrahlung contribution (and more generally the contribution to this part from 2→3 parton subprocesses) is shown to arise from expressions remarkably simple and general.
