Description
It is discussed the problem of the ρ+-ρ0 mass splitting. It is suggested to use the φ→ρπ→3π decay to measure the ρ+-ρ0 mass splitting. In the framework of the SU(3) theory with the U - spin invariance of electromagnetic interactions, taking into account the ideal ω-φ mixing it was obtained expression for the ρ0-ω mixing
Abstract (Russian)
В рамках SU(3) теории с U - спиновой инвариантностью электромагнитных взаимодействий и с учетом идеального ω-φ смешивания было получено выражение для ρ0-ω смешивания. В настоящей работе обсуждается проблема массового расщепления ρ+-ρ0. Для измерения этой величины предлагается использовать распад φ→ρπ→3πAdditional details
