| תקציר: | All the dynamics in the Standard Model of Particle Physics and in General Relativity is described in the framework of relativistic quantum field theory. String field theory, a quantum gauge theory of string fields, was developed with the goal of giving a complete self-consistent framework to string theory. As of 2024 we finally have string field theories for all known versions of string theory. I will describe these theories and the challenges surmounted to achieve their construction. We will also look at lessons learned and future directions. |
