Λ_b \to ΛJ/ψdecay in perturbative QCD
Chung-Hsien Chou, Hsien-Hung Shih, Shih-Chang Lee +1
We calculate the amplitudes involved in the heavy baryon nonleptonic decay $Λ_b \rar ΛJ/ψ$ using perturbative QCD factorization theorem, which are expressed as convolutions of hard…
Polarized decay in perturbative QCD
Hsien-Hung Shih, Shih-Chang Lee, Hsiang-nan Li
We study the polarized baryon semileptonic decay using perturbative QCD factorization theorem. In this approach heavy baryon transition form factors are…
Applicability of perturbative QCD to decays
Hsien-Hung Shih, Shih-Chang Lee, Hsiang-nan Li
We develop perturbative QCD factorization theorem for the semileptonic heavy baryon decay , whose form factors are expressed as the convolutions of hard qua…
The decay in perturbative QCD
Hsien-Hung Shih, Shih-Chang Lee, Hsiang-nan Li
We develop perturbative QCD factorization theorems for the exclusive semileptonic heavy baryon decay , in which the relevant hadronic form factor is expressed as…
The Okubo relation for the baryon magnetic moments and chiral perturbation theory
J. W. Bos, D. Chang, S. C. Lee +1
We analyze the Okubo SU(3) relation among the hyperon magnetic moments in the usual scheme of chiral perturbation theory (ChPT). We classify the one-loop diagrams, including those…
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…
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…
Renormalization of
H. H. Shih, Y. C. Lin
We derive the vertices of five-meson and seven-meson anomaly processes from the four dimensional expansion form of Wess-Zumino term. Using these vertices we calculate the amplitude…
Baryon Chiral Perturbation Theory up to Next-to-Leading Order
J. W. Bos, D. W. Chang, S. C. Lee +2
We examine the general lagrangian for baryon chiral perturbation theory with SU(3) flavor symmetry, up to the next-to-leading order. We consider both the strong and the weak intera…
Cross section for in chiral perturbation theory
J. W. Bos, Y. C. Lin, H. H. Shih
We give the amplitude for in leading order chiral perturbation theory. For the case of real photons we calculate the total and differential cross section.…
