从强子原子能级位移中提取强子-核相互作用信息
On extracting information about hadron-nuclear interaction from hadronic atom level shifts
摘要：
有人认为，直接调整强势观测到的强子原子能级位移可能会导致显着不同的散射长度，比那些，由Deser公式预测。本文以K介子氢的1 s能级移动为例，论证了通常采用的由最近两次KEK测量和DEAR合作组$a_D({\rm KEK}) = 0.78 - 0.49i$ fm和$a_D({\rm DEAR}) = 0.47 - 0.3i$ fm导出的Deser值，应相应地用$a_s({\rm KEK})\simeq 0.85 - 0.62i$ fm和$a_s({\rm DEAR})\simeq 0.49 - 0.35i$ fm代替。
英文摘要：
It is argued, that adjusting strong potentials directly to observed hadronic atom level shifts may lead to significantly different scattering lengths, than those, predicted by the Deser formula. On the example of the 1s level shift of kaonic hydrogen it is demonstrated, that the usually adopted Deser values deduced from the two recent measurements in KEK and by the DEAR Collaboration $a_D({\rm KEK}) = 0.78 - 0.49i$ fm and $a_D({\rm DEAR}) = 0.47 - 0.3i$ fm should be replaced by $a_s({\rm KEK})\simeq 0.85 - 0.62i$ fm and $a_s({\rm DEAR})\simeq 0.49 - 0.35i$ fm, correspondingly.
