对文章“从极化3 He的自旋弛豫对核子-核子偶极-偶极(类轴子)P,T-非不变相互作用的限制”的评论。N. Pokotilovski arXiv:0902.1682v2 [nucl-ex] 2009年2月12日

Comment for article "Limits on a nucleon-nucleon monopole-dipole (axionlike) P,T-noninvariant interaction from spin relaxation of polarized 3He" Yu. N. Pokotilovski arXiv:0902.1682v2 [nucl-ex] 12 Feb 2009

摘要:

在文章“极限对核子-核子偶极偶极子(axionlike)P,T-非不变的相互作用从自旋弛豫极化3 He”Yu。N. Pokotilovski arXiv:0902.1682v2 [nucl-ex] 2009年2月12日提出了标量和伪标量无量纲常数乘积的新约束:gs*gp < 1*10^-17,参数lam约为10^-4 cm,决定了力的范围。在这篇评论中,我们指出,对于来自相同实验数据的相同参数lam,真实约束约为2*10^-11。UCN退极化的约束比它差了约一百倍,不能作为核子-核子偶极(类轴子)P,T非不变相互作用的新极限。

英文摘要:

In article "Limits on a nucleon-nucleon monopole-dipole (axionlike) P,T-noninvariant interaction from spin relaxation of polarized 3He" Yu. N. Pokotilovski arXiv:0902.1682v2 [nucl-ex] 12 Feb 2009 it was presented new constraints for the product of the scalar, pseudo-scalar dimensionless constants: gs*gp < 1*10^-17 for the parameter lam about 10^-4 cm, determining the range of forces. In this comment it is shown that the real constraint for the same parameter lam from the same experimental data is about 2*10^-11. It is worse in about one hundred times that the constraint from UCN depolarization and can not be considered as a new limit on a nucleon-nucleon monopole-dipole (axionlike) P,T-noninvariant interaction.
