Search for ∆S = 2 nonleptonic hyperon decays Ω − → Σ0 π − and Ω − → nK −

Journal of High Energy Physics
Using (27.12 ± 0.14) × 108 ψ(3686) events collected by the BESIII detector at the center-of-mass energy of s $$ \sqrt{s} $$ = 3.686 GeV, we search for the first time for two nonleptonic hyperon decays that change strangeness by two units, Ω − → Σ0 π ...

Exploring the possible two-proton radioactivity of 38,39Ti

Physics Letters B
Two-proton (2p) radioactivity represents a rare decay mode that has been experimentally observed only in a selected few nuclei. The exploration of 2p emission is crucial for elucidating the structure, mass, and nucleon-nucleon interactions within exotic ...

Exploratory calculation of the rare hyperon decay Σ+ → pℓ + ℓ − from lattice QCD

Journal of High Energy Physics
The rare hyperon decay Σ+ → pℓ + ℓ − is a flavour-changing neutral current process mediated by an s → d transition that occurs only at loop level within the Standard Model.

The evidence of N = 16 shell closure and β-delayed neutron emission from 25F

Physics Letters B
We measured the β-delayed neutron emission from 25F for the first time at the Facility for Rare Isotope Beams (FRIB). Using combined neutron and γ-ray detector systems of the FRIB Decay Station Initiator (FDSi), we observed β-decay transitions populating
