What do the phenomenologists of unified theories (strings, loops etc) try to match at lower energies when there are so many conflicting theories lying around at these energies?
I understand that certain things should be there in any model - like chiral matter, three generations etc - but a lot of things still remain unsettled (like right-handed neutrinos, the GUT gauge group etc).
