Decay constants, light quark masses and quark mass bounds from light quark pseudoscalar sum rules
Kim Maltman, Joachim Kambor
The flavor and pseudoscalar correlators are investigated using families of finite energy sum rules (FESR's) known to be very accurately satisfied in the isovector vector…
On the longitudinal contributions to hadronic tau decay
Kim Maltman, Joachim Kambor
A number of recent determinations of using hadronic decay data involve inclusive analyses based on the so-called spectral weights. We show here that the OPE repre…
m_u+m_d From Isovector Pseudoscalar Sum Rules
Kim Maltman, Joachim Kambor
We revisit the isovector pseudoscalar sum rule determination of m_u+m_d, using families of finite energy sum rules known to be very accurately satisfied in the isovector vector cha…
A note on the dispersive treatment of K -> pi pi with the kaon off-shell
M. Buechler, G. Colangelo, J. Kambor +1
It has been recently suggested that it is possible to calculate the effect of final state interactions in K -> pi pi amplitudes by applying dispersive methods to the amplitude with…
Dispersion relations and soft pion theorems for K -> pi pi
M. Buechler, G. Colangelo, J. Kambor +1
We propose a new method to obtain the K -> pi pi amplitude from K -> pi which allows one to fully account for the effects of final state interactions. The method is based on a set…
Reordering of Baryon Chiral Perturbation Theory
Martin Mojzis, Joachim Kambor
Reordering of the chiral perturbation series, proposed recently by Becher and Leutwyler in the framework of SU(2) baryonic ChPT, is applied to the SU(3) case. This results in impro…
