Investigation of vacuum melting technique for low background titanium
He jishu, 2022 BackgroundThe expected signal rate of rare decay experiments, such as instance dark matter and neutrino less double beta decay experiments, is extremely low, which requires that the detector building materials have extremely low radioactivity.

Top quark decays with flavor violation in the B-LSSM
European Physical Journal C: Particles and Fields, 2018 The decays of top quark $$t\rightarrow c\gamma ,\;t\rightarrow cg,\;t\rightarrow cZ,\;t\rightarrow ch$$ t→cγ,t→cg,t→cZ,t→ch are extremely rare processes in the standard model (SM).

Light gauge boson in rare K decay
Physics Letters B, 2016 We study the production of a light gauge boson in K−→π−X decay, where the associated new charge current is not conserved. It is found that the process can be generated by the tree-level W-boson annihilation and loop-induced s→dX. We find that it strongly

The European Physical Journal C, 2003 The Kloe experiment has collected an integrated luminosity ~ 500 pb–1 up to now, which means ~ 1.65×109 φ decays. The huge amount of events allowed us to measure rare φ decays. We measured the radiative decays of the φ meson into π0, η and η′(958). These measurements are relevant to assess the mixing in the pseudoscalar nonet as well as to evaluate the

Annual Review of Nuclear and Particle Science, 2021 Historically important in the development of the Standard Model (SM) of particle physics, rare kaon decays are still a privileged tool for looking beyond it. The main reasons to continue the study of rare kaon decays are to test the CKM quark-mixing and CP-violation paradigm, to make quantitative comparisons with the B sector, and to search for ...

Proceedings of The 13th International Conference on B-Physics at Hadron Machines — PoS(BEAUTY 2011), 2011 Rare radiative, leptonic and semileptonic B meson decays are valuable probes of physics beyond the Standard Model. This talk reviews the sensitivity to new physics of observables related to two rare B decays to be measured in the near future at LHC, B(s) -> mu+ mu- and B -> K* mu+ mu-.

European Physical Journal C: Particles and Fields, 2023 A first search for rare decays of gadolinium isotopes was performed with an ultra-low background high-purity germanium detector at Gran Sasso Underground Laboratory (Italy). A 198 g $$\hbox {Gd}_2$$ Gd 2 $$\hbox {O}_3$$ O 3 powder sample was measured for

Kaons at CERN: recent results and prospects
EPJ Web of Conferences, 2014 The NA48/2 and NA62 experiments at CERN study rare kaon decays using the decay in flight technique. In this paper two selected topics will be presented: new measurements performed by the two experiments of the K±→ π±γγ decay which represents a stringent ...

Rare weak decays and nuclear structure
EPJ Web of Conferences, 2014 Weak interactions cause the atomic nuclei to decay via beta and double beta decays. Double beta decays are extremely rare since they are weak-interaction processes of the second order. Also (single) beta decays can be extremely rare.

Moscow University Physics Bulletin, 2022 The Standard Model (SM) of particle physics is the most advanced theory describing the behaviour and interactions of elementary particles. Despite passing an impressive amount of experimental tests, several deviations from the SM predictions have been observed in recent years in measurements of observables related to rare $b$-hadron decays, prompting ...
