SUMMARY:Breeding and bounding intersecting branes\, Thesis Defense\, G
 regory Loges\, Physics PhD Graduate Student
DESCRIPTION:Intersecting branes provide a natural framework for constr
 ucting four-dimensional theories with semi-realistic particle physics.
  The phenomenological properties of vacua built in this way vary drama
 tically\, and it is an interesting task to understand both what is pos
 sible and what is typical. I will discuss intersecting brane construct
 ions for type IIA string theory on a toroidal orbifold from two perspe
 ctives. On one hand\, genetic algorithms\, which take inspiration from
  nature\, provide a method to optimize desirable properties by "breedi
 ng" a population of branes. Generation by generation\, random samples 
 are produced and the underlying structure learned. On the other\, an e
 xact number of indistinguishable vacua can be found by leveraging the 
 recursive way in which branes are combined. Sharp predictions for modu
 li\, gauge group\, etc. can be obtained at the cost of losing detailed
  information about any one vacuum.
