对K+→ π+ X衰变的搜索，其中X是一种长寿命的弱相互作用粒子，通过对2017年欧洲核子研究中心NA 62实验收集的数据进行K+→分析来进行。两个范围的X质量，0-110 MeV/c2和154-260 MeV/c2，和寿命超过100 ps被认为是。对分支比BR（K+→ π+ X）设定的限制与先前报道的第一质量范围内的搜索具有竞争力，并且比第二质量范围内的当前限制提高了一个数量级以上。
A search for the K+→ π+ X decay, where X is a long-lived feebly interacting particle, is performed through an interpretation of the K+→analysis of data collected in 2017 by the NA62 experiment at CERN. Two ranges of X masses, 0–110 MeV/c 2 and 154–260 MeV/c 2, and lifetimes above 100 ps are considered. The limits set on the branching ratio, BR (K+→ π+ X), are competitive with previously reported searches in the first mass range, and improve on current limits in the second mass range by more than an order of magnitude.
