On the extraction of the quark mass ratio (m_d-m_u)/m_s from gamma (eta` to pi0 pi+ pi-)/gamma (eta` to eta pi+ pi-)
On the extraction of the quark mass ratio (m_d-m_u)/m_s from gamma (eta` to pi0 pi+ pi-)/gamma (eta` to eta pi+ pi-)
The claim that the light quark mass ratio (m(d) - m(u))/m(s) can be extracted from the decay width ratio Gamma(eta' -> pi(0)pi(+)pi(-))/Gamma(eta' -> eta pi(+)pi(-)) is critically investigated within a U(3) chiral unitary framework. The influence of the recent VES data on the eta...

The claim that the light quark mass ratio (m(d) - m(u))/m(s) can be extracted from the decay width ratio Gamma(eta' -> pi(0)pi(+)pi(-))/Gamma(eta' -> eta pi(+)pi(-)) is critically investigated within a U(3) chiral unitary framework. The influence of the recent VES data on the eta' -> eta pi(+)pi(-) decay is also discussed. (c) 2006 Elsevier B.V. All rights reserved. |
