New high precision study on the decay width of the Hoyle state in 12C

open access: yesPhysics Letters B, 2019
Precise estimation of the rare direct 3α decay of the Hoyle state of 12C has been made to unveil its unusual α-cluster configurations ranging from linear 3α chain structure to diffuse Bose gas as well as Bose Einstein condensate.

Space–time evolution of heavy sterile neutrinos in cascade decays

open access: yesNuclear Physics B, 2014
Heavy sterile-like neutrinos may be produced resonantly from the decay of pseudoscalar mesons and may decay into several different channels in a cascade Φ→Lανh; νh→{X}. In general these are rare events with displaced vertices.

Beyond the Standard Model prospects for kaon physics at future experiments

open access: yesJournal of High Energy Physics
Rare kaon decays offer a powerful tool for investigating new physics in s → d transitions. Currently, many of the interesting decay modes are either measured with rather large uncertainties compared to their theoretical predictions or have not yet been ...

Rare Kaon Decays

open access: yes, 2022
The experimental status of the $K \to πν\barν$ search is presented. The $K \to πν\barν$ decay is sensitive to New Physics because it is theoretically pristine and highly suppressed. The $K_L^0 \to π^0 ν\barν$ search is performed by the KOTO experiment and a branching fraction limit of $\mathcal{B}(K_L^0 \to π^0 ν\barν)$ $<$ 3.0 $\times$ 10$^{-9 ...

Search for K+ → π+νν̄ at the NA62 experiment

open access: yesEPJ Web of Conferences, 2016
Looking for phenomena beyond the Standard Model (SM) in rare decays is a complementary approach to direct searches for New Physics (NP) at colliders. One of the theoretically cleanest processes is the ultra rare decay K+ → π+νν̄.

Rare Charm Decays [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 2005
Rare FCNC decay modes of charmed mesons are reviewed. The standard model predictions, including both short and long distance contributions, are summarized. Several new physics options that can give detectable signals are described.

Search for the semi-muonic charmonium decay J/ψ → D − μ + ν μ + c.c.

open access: yesJournal of High Energy Physics
Using (10087 ± 44) × 106 J/ψ events collected with the BESIII detector at the BEPCII e + e − storage ring at the center-of-mass energy of s $$ \sqrt{s} $$ = 3.097 GeV, we present a search for the rare semi-muonic charmonium decay J/ψ → D − μ + ν μ + c.c..

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

open access: yesJournal 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 ...
