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 ...

K± → π± π0 e+ e− decay width calculation in the lepton center-of-mass system
EPJ Web of Conferences, 2014 We consider the rare decay K± → π± π0 e+ e− currently under analysis by the NA62 Collaboration. A new theoretical approach for the differential decay width has been performed.

, 2012 We present a systematic light-cone QCD sum rule study of the exclusive rare radiative decay $\Lambda_b\rightarrow\Lambda\gamma$ and rare semileptonic decay $\Lambda_b\rightarrow\Lambda l^+l^-$ within the framework of the standard model.

Rare beauty and charm decays at LHCb
EPJ Web of Conferences, 2013 Rare heavy flavor decays are an ideal place to search for the effects of potential new particles that modify the decay rates or the Lorentz structure of the decay vertices. The LHCb experiment, a dedicated heavy flavour experiment at the LHC at CERN.

Review of Rare and Forbidden $\tau$ Decays
, 1997 This is a review of rare and forbidden decays of the $\tau$ lepton. For the rare decays, this includes new results on the chiral anomaly decay $\taupietapio$, new upper limits on the second-class-current decay $\taupieta$, and the observations of the ...

Comptes Rendus. Physique, 2020 The article reviews the status of rare K decay physics. The explored area covers a broad program, ranging from precise tests of flavour theory and CP-violation to the searches for explicit violations of the standard model and the study of strong interactions at low energies.
