摘要:

QCD结果提出了2+1味费米子三叶草行动(我们称之为SLiNC行动)。讨论了将夸克质量调整到其物理值的方法。在该方法中,单重态夸克质量保持不变,解决了非手征不变格点费米子的重整化(单重态和非单重态夸克质量)不同的问题。这个过程可以探测大范围的夸克质量,包括重上下夸克质量和轻奇异夸克质量的情况。初步结果显示了重子(八重态和十重态)谱的正确分裂。

英文摘要:

QCD results are presented for a 2+1 flavour fermion clover action (which we call the SLiNC action). A method of tuning the quark masses to their physical values is discussed. In this method the singlet quark mass is kept fixed, which solves the problem of different renormalisations (for singlet and non-singlet quark masses) occuring for non-chirally invariant lattice fermions. This procedure enables a wide range of quark masses to be probed, including the case with a heavy up-down quark mass and light strange quark mass. Preliminary results show the correct splittings for the baryon (octet and) decuplet spectrum.
