The Standard Model from string theory D-branes

by Angel Uranga (Madrid)



I will review the recent attempts to embed the Standard Model of Particle Physics (and supersymmetric extensions thereof) in string theory, using D-branes. The gauge interactions and elementary fermions arise as different kinds of open strings stretched between the D-branes in the configurations. I will discuss the main phenomenological properties of such string models, and how close to the actual Standard Model they get.
