通过对低能量K{sup -}p散射数据的大量拟合，用手性SU(3)酉方法提取了强K{sup -}p散射长度。得到的散射长度与现有的散射数据总体上符合得很好，并与新得到的精确kaonic氢数据进行了比较。对得到的实验拟合的极点结构进行了严格的检验。
The strong K{sup -}p scattering length is extracted within chiral SU(3) unitary approaches from a very large variety of fits to low-energy K{sup -}p scattering data. Very good overall agreement with available scattering data is obtained and the resulting scattering length is compared with the new accurate kaonic hydrogen data from DEAR. The pole structures of the obtained fits to experiment are critically examined.
