Low order mass spectrum constraints from an SU(3) × SU(3) chiral algebra mixing operator
Abstract
It has been proposed that a unitary operator, U( θ), connects axial charges with the generators A( λ_{i}σ_{z}) of SU(6) and the form of this operator has been partially determined up to second order using a perturbative approach. We obtain the details of this operator and then apply it to find its implications on the mass spectrum at low order in θ. In particular we find the (mass) ^{2} equation 3 m_{B}^{2} = 2 m_{A 2}^{2} + m_{A 0}^{2} holds up to corrections of order θ^{4}.
