    Description
    MSFT is an alternative formulation of Witten's cubic string field theory. The main novelty is that string joining is formulated as the simple Moyal product. Its advantage is that it is much simpler for practical computations, while fully agreeing with former approaches, such as the oscillator formulation or conformal field theory formulation. In this lecture I will describe the main ideas, structure and goals of the theory, and will report on new results for off-shell string amplitudes that were not obtained in other approaches in string field theory.
