Pseudo-anomalous U(1) symmetry in the strong coupling limit of the heterotic string

P. Binetruy, C. Deffayet, E. Dudas +1

We discuss, in the context of the strongly coupled E_8 \times E_8 heterotic string proposed by Horava and Witten, the appearance of anomalous U(1)_X symmetries of a nonperturbative…
