Rare φ decays

open access: yesThe 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

Rare Kaon Decays [PDF]

open access: yesAnnual 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 ...

Rare Decays at LHCb

open access: yesEPJ Web of Conferences, 2014
Rare decays of beauty and charm hadrons provide an effective method of testing the Standard Model and probing possible new physics scenarios. The LHCb experiment has published a variety of interesting results in this field, some of which are presented ...

A search for flavour changing neutral currents in top-quark decays in pp collision data collected with the ATLAS detector at s√=7TeV [PDF]

open access: yes, 2012
A search for flavour changing neutral current (FCNC) processes in top-quark decays by the ATLAS Collaboration is presented. Data collected from pp collisions at the LHC at a centre-of-mass energy of s√=7TeV during 2011, corresponding to an integrated ...

Insights on the current semi-leptonic B-decay discrepancies — and how B s → μ + μ − γ can help

open access: yesJournal of High Energy Physics, 2023
B s → μ + μ − γ, measured at high q 2 as a partially reconstructed decay, can probe the origin of the existing discrepancies in semi-leptonic b → s and b → c decays. We perform a complete study of this possibility.

Rare decays: Experiments

open access: yesZeitschrift für Physik C Particles and Fields, 1992
The experimental status of generation number violating muon and kaon decays is reviewed. We concentrate on three experiments with a large PSI contribution, neutrinoless muon-electron conversion, muonium-antimuonium conversion and the decay K+ --> pi+mu(e).

From D s → γ in lattice QCD to B s → μμγ at high q 2

open access: yesJournal of High Energy Physics, 2023
We use a recent lattice determination of the vector and axial D s → γ form factors at high squared momentum transfer q 2 to infer their B s → γ counterparts. To this end, we introduce a phenomenological approach summarized as follows.

Search for top quark decays t → qH with H → γγ using the ATLAS detector [PDF]

open access: yes, 2014
A search is performed for flavour-changing neutral currents in the decay of a top quark to an up-type (c, u) quark and a Higgs boson, where the Higgs boson decays to two photons.
