论文摘要

与陌生性$ s = -1 $区域的超核互动相互作用很复杂且难以调查,因为它的风味部门涉及所有不可减至的表示,除了风味单线,并且在陌生区域之间具有最差的信噪比。为了克服此类困难,本报告的内容是双重的:(i)我们提出了扩展有效的Baryon块算法的实现。 (ii)我们在几乎物理夸克质量上对$λn$系统进行单通道分析,对应于$(m_π,m_k)\大约(146,525)$ 〜MEV和大容量$(la)^4 =(96aa)^4 \ $(96a)^4 $(8.1 fm)$(146,525)$(146,525)$(146,525)$(146,525)$(146,525)$(146,525)$(146,525)$^4 $^4 $^4 $^4 $^4 $^4 $^4.提出了$λn$系统的散射相移。

The hyperon-nucleon interaction with the strangeness $S=-1$ region is complicated and difficult to investigate because its flavor sector involves all the irreducible representation except the flavor singlet and has the worst signal-to-noise ratio among the strangeness regions. In order to overcome such difficulties the content of this report is twofold: (i) We present an implementation of extended effective baryon block algorithm. This is a straightforward extension of the original which was reported in LATTICE 2013. (ii) We perform single channel analysis for the $ΛN$ system at nearly physical quark masses corresponding to $(m_π,m_K)\approx(146,525)$~MeV and large volume $(La)^4=(96a)^4\approx$ (8.1 fm)$^4$. Scattering phase shifts for $ΛN$ system are presented.
