RARE b DECAYS [PDF]

open access: yesInternational Journal of Modern Physics A, 1995
Rare b decays provide a unique opportunity to measure Standard Model parameters and probe beyond the Standard Model. We review here the experimental progress made in measuring these decays, and the importance of future measurements, including the possible observation of CP violation.

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).

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.

Rare B decays at LHCb [PDF]

open access: yes, 2022
Rare decays are flavour changing neutral current processes that allow sensitive searches for phenomena beyond the Standard Model (SM). In the SM, rare decays are loop-suppressed and new particles in SM extensions can give significant contributions.

First observation of the decays B0 -> D+K-π+π- and B- -> D0K-π+π- [PDF]

open access: yes, 2012
First observations of the Cabibbo-suppressed decays B0→D+K-π+π- and B-→D0K-π+π- are reported using 35pb -1 of data collected with the LHCb detector. Their branching fractions are measured with respect to the corresponding Cabibbo-favored decays, from ...

Flavor physics in the quark sector [PDF]

open access: yes, 2008
In the past decade, one of the major challenges of particle physics has been to gain an in-depth understanding of the role of quark flavor. In this time frame, measurements and the theoretical interpretation of their results have advanced tremendously. A

Complete analysis on QED corrections to B q → τ + τ −

open access: yesJournal of High Energy Physics, 2023
Motivated by a dynamical enhancement of the electromagnetic corrections by a power of ΛQCD/m b in B d,s → μ + μ − at next-to-leading order (NLO), we extend the QED factorization effects on the leptonic B meson decays with light muon leptons to tauonic ...

Branching fraction and CP asymmetry of the decays B+→K0Sπ+ and B+→K0SK+ [PDF]

open access: yes, 2013
An analysis of B+ → K0 Sπ+ and B+ → K0 S K+ decays is performed with the LHCb experiment. The pp collision data used correspond to integrated luminosities of 1 fb−1 and 2 fb−1 collected at centre-ofmass energies of √ s = 7 TeV and √ s = 8 TeV ...

Rare B decays [PDF]

open access: yesProceedings 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-.
