Revisiting the number-theory dark matter scenario and the weak gravity conjecture

We revisit the number-theory dark matter scenario where one of the light chiral fermions required by the anomaly cancellation conditions of U(1)B-L explains dark matter. Focusing on some of the integer B-L charge assignments, we explore a new region of the parameter space where there appear two ligh...
