Constraints on chiral indices from the condition of no chiral exotics #
On the types FluxesFive
and FluxesTen
, we have the conditions NoExotics
,
corresponding to the non-existence of chiral exotics in the spectrum.
These conditions lead to constraints of the chiral indices of the SM representations. For example:
- They must be non-negative.
- They must be less than or equal to
3
. - The non-zero chiral indices must be one of the following multisets
{1, 1, 1}
,{1, 2}
,{3}
.
This module proves these constraints.
Constraints on the chiral indices of D = (bar 3,1)_{1/3}
#
The chiral indices of the representations D = (bar 3,1)_{1/3}
are all non-negative if

The sum of the chiral indices of the representations D = (bar 3,1)_{1/3}
is equal
to 3
in the presences of no exotics.
The chiral indices of the representation D = (bar 3,1)_{1/3}
are less then
or equal to 3
