H. Kataoka, M. Shimojo
TL;DR
This paper investigates intersecting D4- and D5-brane models in string theory, identifying configurations that produce Standard Model-like particle content and analyzing RR tadpole cancellation conditions.
Contribution
It provides a comprehensive analysis of D4-brane models with three-generation chiral fermions and presents a specific D5-brane solution matching the Standard Model matter content.
Findings
D4-brane models with three generations and Standard Model gauge symmetries identified
A D5-brane configuration that reproduces Standard Model matter content with U(1) anomalies
Clarification of RR tadpole cancellation conditions for these intersecting brane models
Abstract
We clarify RR tadpole cancellation conditions for intersecting D4-/D5-branes. We find all of the D4-brane models which have D=4 three-generation chiral fermions with the SU(3)XSU(2)XU(1)^n symmetries. For the D5-brane case, we present a solution to the conditions which gives exactly the matter contents of standard model with U(1) anomalies.
