Diagonal versus nondiagonal couplings of ψ particles

Research output: Contribution to journalArticlepeer-review

Abstract

In essentially all common models of the ψ particles off-diagonal couplings such as ψ′ψππ are expected to be greatly suppressed relative to diagonal couplings such as ψψππ. We point out that this is counter-indicated by the data, leading to important constraints on model building.
