D-Branes, Tachyons, and String Field Theory
by Washington Taylor, Barton Zwiebach
Publisher: arXiv 2004
Number of pages: 104
In these notes we provide a pedagogical introduction to the subject of tachyon condensation in Witten's cubic bosonic open string field theory. We use both the low-energy Yang-Mills description and the language of string field theory to explain the problem of tachyon condensation on unstable D-branes.

This short book is an introduction to some recent developments in string theory and M theory. The author tries to concentrate on the main physical aspects, and often leaves more technical details to the original literature.
