There is a brilliant curiosity in bettering the bounds on neutron lifetime to the extent of a precision of 0.1 s. The neutron lifetime is either an immense basic volume in addition to a parameter influencing very important methods resembling nucleosynthesis (Helium creation within the early universe) and the speed of strength construction within the Sun.

Aiming to create a roadmap of R&D for a subsequent iteration neutron lifetime test that may be recommended by way of the North American neutron neighborhood, the point of interest of the workshop was once on experiments utilizing traps that make the most of ultracold neutrons and confinement via a mix of magnetic and/or gravitational interplay in an effort to keep away from systematic uncertainties brought via neutron interactions with fabric partitions. The papers during this quantity summarize the constraints of current experiments, the dialogue of recent experiments in strategy planning stage, and the dialogue of systematic results that has to be addressed to accomplish a life-time dimension at an accuracy of 0.1 second.
