SU(3) Breaking in Neutral Current Axial Matrix Elements and the Spin Content of the Nucleon

Martin J. Savage, James Walden

We examine the effects of SU(3) breaking in the matrix elements of the flavour-diagonal axial currents between octet baryon states and find that SU(3) breaking may be substantial f…

Large-N_c Relations Among Isgur-Wise Functions

David E. Brahm, James Walden

We investigate the relations that must hold among baryonic Isgur-Wise functions $η_{i}$ in the large-N_c limit from unitarity constraints, and compare to those found by Chow using th…

The Radiative Charmed Baryon Decay $Ξ_{c 2}^{0 *} \to Ξ_{c 1}^{0} γ$

Ming Lu, Martin J. Savage, James Walden

V-spin symmetry ( $s \leftrightarrow d$ symmetry) forbids the radiative decay $Ξ_{c 2}^{0 *} \to Ξ_{c 1}^{0} γ$ in the SU(3) limit. The quark mass term breaks V-spin symmetry and…

Final State Interactions and CP Violation in $K_{L} \to π^{+} π^{-} e^{+} e^{-}$

John K. Elwood, Mark B. Wise, Martin J. Savage +1

Using chiral perturbation theory we calculate the imaginary parts of the $K_{L} \to π^{+} π^{-} e^{+} e^{-}$ form factors that arise from $π π \to π^{+} π^{-}$ and $ππ\rightarrow π…
