## Prompt

MIRROR FERMIONS — F-THEORY COMPLETION
In the E8 gauge sector, the branching E8 superset E6xSU(3) leaves 27+27* representations. Identify the 27* as mirror fermions. Compute their mass spectrum from the J3(Os)* conjugate algebra. Show mirror fermions acquire masses at the G2(2) scale (~165 GeV) and are therefore LHC-accessible. Predict production signatures. #SuperGrokTOE #MirrorFermions #BSM #Ftheory
