Improved Standard-Model prediction for K L → ℓ + ℓ −

open access: yesJournal of High Energy Physics
We present a comprehensive calculation of the K L → γ ∗ γ ∗ form factor in dispersion theory, using input from the leptonic decays K L → ℓ + ℓ − γ, $${K}_{L}\to {{\ell}}_{1}^{+}{{\ell}}_{1}^{-}{{\ell}}_{2}^{+}{{\ell}}_{2}^{-}$$ , the hadronic mode K L ...

Rare kaon decays

open access: yesComptes 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 ...

B → K∗µ+µ− and Form Factors for Semi-Leptonic and Radiative B Decays [PDF]

open access: yes, 2010
The hadronic environment of the LHC favours the study of exclusive modes, and of these semi-leptonic and radiative B decays will play a leading role in the search for new physics (NP).

An easyguide to rare diseases in Ireland and consensus for action for government, the general public, media and political parties [PDF]

open access: yes, 2020
The aims of this guide are to: • Explain what a rare disease is and how it is defined in health policy • Provide insights into living with a rare disease • Identify priorities patient advocacy groups would urge the Irish Government to include in the

Amplitude analysis of B^{0}→K^{+}π^{-}π^{0} and evidence of direct CP violation in B→K*π decays [PDF]

open access: yes, 2011
We analyze the decay B(0) -> K(+) pi(-) pi(0) with a sample of 4.54 x 10(8) B (B) over bar events collected by the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC, and extract the complex amplitudes of seven interfering resonances over ...

Uniting low-energy semileptonic and hadronic anomalies within SMEFT

open access: yesJournal of High Energy Physics
Two categories of four-fermion SMEFT operators are semileptonic (two quarks and two leptons) and hadronic (four quarks). At tree level, an operator of a given category contributes only to processes of the same category.

Rare $b$-hadron decays

open access: yesComptes Rendus. Physique, 2020
Rare $b$-hadron decays provide a rich environment to search for beyond Standard Model physics effects thanks to numerous observables. In the recent years, several tensions with the SM expectations have appeared.

FCNC B and K meson decays with light bosonic Dark Matter

open access: yesJournal of High Energy Physics, 2023
We consider decays of B and K mesons into a pseudo-scalar or vector meson plus missing energy. Within the SM, these modes originate from flavor changing neutral current (FCNC) processes with two neutrinos in the final state. In this paper we consider the

Theory of rare B decays [PDF]

open access: yesAIP Conference Proceedings, 1995
Theoretical aspects of rare $B$ decays are reviewed. The focus is on the relation between short-distance interactions and physical observables. It is argued that there remain significant uncertainties in the theoretical treatment of certain important quantities.

Searches for B0(s)→J/ψppˉ and B+→J/ψppˉπ+ decays [PDF]

open access: yes, 2013
The results of searches for B0(s)→J/ψ pp¯ and B + → J/ψ p p¯ π+ decays are reported. The analysis is based on a data sample, corresponding to an integrated luminosity of 1.0 fb−1 of pp collisions, collected with the LHCb detector.
