超子正向自旋极化率gamma0
Hyperon forward spin polarizabilty gamma0
摘要：
在SU（3）重子手征微扰理论（HBChPT）的框架下，系统地计算了超子康普顿散射的首阶数，并提取了超子的前向自旋极化率γ 0.当不考虑K介子环时，在核子情况下对γ 0的结果与SU（2）HBChPT的已知结果一致.
英文摘要：
We present the results of a systematic leading order calculation of hyperon Compton scattering and extract the forward spin polarizability gamma0 of hyperons within the framework of SU(3) heavy baryon chiral perturbation theory (HBChPT). The results obtained for gamma0 in the case of nucleons agree with that of the known results of SU(2) HBChPT when kaon loops are not considered.
