  Over the past decade, massive modeling practices on low temperature plasma
(LTP) reveal that input data such as microscopic scattering cross sections are
crucial to output macroscopic phenomena. In Monte Carlo collision (MCC)
modeling on LTP, angular scattering model is a non-trivial topic in both
natural and laboratory plasma. Conforming to the pedagogical purpose of this
overview, the classical and quantum theory of binary scattering including the
commonly used Born-Bethe approximation is first introduced. State-of-the-art
angular scattering models are derived based on the above theories for
electron-neutral, ion-neutral, neutral-neutral, and Coulomb collisions. The
tutorial is not aiming to provide accurate cross section data by modern
approaches in quantum theory, but to introduce analytical angular scattering
models from classical, semi-empirical, and first-order perturbation theory. The
reviewed models are expected to be readily incorporated into the MCC codes, in
which scattering angle is randomly sampled through analytical inversion instead
of numerical accept-reject method. Those simplified approaches are very
attractive, and demonstrate in many cases the ability to achieve a striking
agreement with experiments. Energy partition models on electron-neutral
ionization are also discussed with insight from the binary encounter Bethe
theory. This overview is written in a tutorial style, in order to serve as a
guide for novice in this field, and at the same time as a comprehensive
reference for practitioners in MCC modeling on plasma.
