Scientists at Osaka University were part of a particle accelerator experiment that produced an exotic and highly unstable particle, and determined its mass. This could contribute to a better understanding of the inner workings of ultra-dense neutron stars. The Standard Model of particle physics e
Researchers have successfully synthesized an exotic, but very short-lived, Lambda resonance known as Λ for the first time.
The Standard Model of particle physics explains that most particles are made of combinations of just six types of basic entities called quarks. However, there are still many unsolved mysteries, one of which is Λ, an exotic but fleeting Lambda resonance. It was previously believed to be a specific combination of three quarks – up, down, and strange – and gaining insight into its composition could assist in uncovering information about the extremely dense matter in neutron stars.
The much more familiar proton that makes up the matter that we are used to has two up quarks and a down quark. The researchers showed that Λ is best thought of as a temporary bound state of the KIn a study published recently in, the group describes the experiment they carried out at the J-PARC accelerator. Kmesons were shot at a deuterium target, each of which had one proton and one neutron.
One of the aspects that had been perplexing scientists about Λ was its very light overall mass, even though it contains a strange quark, which is nearly 40 times as heavy as an up quark. During the experiment, the team of researchers was able to successfully measure the complex mass of Λ by observing the behavior of the decay products.
