The wrong turn of string theory: our world is SUSY at low energies

[QUOTE="arivero, post: 3220031, member: 81"] Currently I am fantasising that at the end of the path we had investigated the case with 16 up quarks and 31 down quarks, producing 16*31 = 496 ud combinations and (31*32)/2 = 496 dd combinations and so 248 generations [SIZE="1"](each generation, of course, needs two scalars to pair each fermion of a given charge)[/SIZE], and then the scalars from the extant (16*17)/2= 136 uu combinations had been used to give mass to some objects, breaking some underlying symmetry group from 248 elements to something with 248 - 136 = 112 elements. Or something so :biggrin: [spoiler][SIZE="1"] the joke was about the decomposition of E8 as a sum of representations of SU(2)xE7, this is (3,1)+(1,133)+(2,56): the whole representation is a 248, while the last subrrep is a 112. If you were guessing other family of objects, please tell me! [/SIZE][/spoiler] [/QUOTE]
