Hi,
there exist tables with group theory breaking patters and branching rules such as
[tex]E_7 \rightarrow E_6 \times U(1)[/tex]
[tex]133 \rightarrow 78 + 1 + 27 + \bar{27}[/tex]
[tex]56 \rightarrow 1 + 1 + 27 + \bar{27}[/tex]
What is missing is the U(1) charge. Does anyone know how to obtain it?
Perhaps it could be done by using a character formula but then I would need the characters of these representations.
Any help would be appreciated.
