Heavy-baryon chiral perturbation theory and reparametrization invariance
J. W. Bos, D. Chang, S. C. Lee +2
We examine the constraints imposed by reparametrization invariance on heavy-baryon chiral perturbation theory (HBChPT). We study the case of 3 flavors and consider both the strong…
New Limits on R-Parity Breakings in Supersymmetric Standard Models
Darwin Chang, W. -Y. Keung
New limits on couplings , which break both the baryon number and the --parity, are derived by using a new mechanism that contributes to the neutron-anti-neutron os…
CP Violation in Hyperon Decays
Darwin Chang, Chuan-Hung Chen
The CP properties in hyperon decays are briefly reviewed. We discuss the general phenomenology and define CP odd observables in hyperon decays. With these observables, we discuss t…
How to Observe the Interference Effects of Top quark polarizations at Tevatron
Darwin Chang
Using a simple analytic expression for with the interference…
SU(3) breaking and baryon magnetic moments
J. W. Bos, D. Chang, S. C. Lee +2
We show that the magnetic moments of the octet baryons can be fitted to an accuracy of 1.5 percent by a phenomenological Lagrangian in which SU(3) breaking corrections appear only…
Hyperon weak radiative decays in chiral perturbation theory
J. W. Bos, D. Chang, S. C. Lee +2
We investigate the leading-order amplitudes for weak radiative decays of hyperons in chiral perturbation theory. We consistently include contributions from the next-to-leading orde…
