手性EFT的不同变体预测质子康普顿微分截面-以及为什么
What different variants of chiral EFT predict for the proton Compton differential cross section - and why
摘要：
我们比较了手征有效场论的不同变体的预测伽玛-p弹性散射微分截面。我们特别注意π介子环的作用，以及重子膨胀对这些环的行为的影响。我们还纠正了Phys.Rev.C67，055202（2003）[ arXiv：nucl-th/0212024 ]中发表的这些循环的错误结果。
英文摘要：
We compare the predictions of different variants of chiral effective field theory for the gamma-p elastic scattering differential cross section. We pay particular attention to the role of pion loops, and the impact that a heavy-baryon expansion has on the behavior of those loops. We also correct erroneous results for these loops that were published in Phys. Rev. C 67, 055202 (2003) [ arXiv:nucl-th/0212024 ].
