The discrepancy in neutron lifetime measurements between storage experiments with ultracold neutrons and beam experiments with cold neutrons has persisted as a significant...
After cooling and trapping, Ultracold Neutrons (UCNs) reacquire kinetic energy over a relatively long period of time. This process is called Small Heating and it is not yet fully understood. Most intriguingly, this process wears off to some extent.
In 2024 we have proposed a dressed quark model that could explain the Neutron Lifetime Puzzle (NLP). The neutrons in the beam could be in so-far...
Koch and Hummel[1] suggest a new solution to the neutron lifetime enigma[2]. The neutron lifetime enigma arises from the 4.4 standard deviation difference between the lifetime measured for bottled neutrons[3] and measurements of lifetime from a beam of cold neutrons[4]. Koch and Hummel point out the beam experiments measure the decay rate of neutrons very close in time to their source whereas...
