Compact F-theory GUTs with U(1)_(PQ)
Journal of High Energy Physics, no. 4 (2010): 95
摘要
We construct semi-local and global realizations of SU(5) GUTs in F-theory that utilize a U(1)PQ symmetry to protect against dimension four proton decay. Symmetries of this type, which assign charges to H
u
and H
d
that forbid a tree level μ term, play an important role in scenarios for neutrino physics and gauge mediation that h...更多
