Towards the MSSM from F-theory
Kang-Sin Choi, Tatsuo Kobayashi
TL;DR
This paper explores how the Minimal Supersymmetric Standard Model (MSSM) can be realized within F-theory, detailing the gauge structure, matter content, and Yukawa couplings consistent with phenomenological requirements.
Contribution
It demonstrates a construction of the MSSM in F-theory with realistic gauge group, matter spectrum, and Yukawa interactions at the renormalizable level.
Findings
MSSM spectrum with three generations derived from F-theory
Realization of Yukawa couplings with matter parity
Gauge group structure consistent with phenomenology
Abstract
We study the MSSM in F-theory. Its group is the commutant to a structure group SU(5) x U(1)_Y of a gauge bundle in E_8. The spectrum contains three generations of quarks and leptons plus vectorlike electroweak and colored Higgses. The minimal MSSM Yukawa couplings with matter parity is obtained at the renormalizable level.
