Lemmas for 1 family SM Accs #
The main result of this file is the conclusion of this paper: Lohitsiri and Tong
That every solution to the ACCs without gravity satisfies for free the gravitational anomaly.
For a set of 1 family SM charges satisfying all ACCs except the gravitational,
the charge of Q is zero if and only if E is zero.
For a set of 1-family SM charges satisfying all ACCs except the gravitational,
if the Q charge is zero then the charges satisfy the gravitational ACCs.
For a set of 1-family SM charges satisfying all ACCs except the gravitational,
if the Q charge is not zero then the charges satisfy the gravitational ACCs.
Any solution to the 1-family ACCs without gravity satisfies the gravitational ACC.
