, 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.

Rare b decays meet high-mass Drell-Yan
Journal of High Energy Physics, 2023 Rare b hadron decays are considered excellent probes of new semileptonic four-fermion interactions of microscopic origin. However, the same interactions also correct the high-mass Drell-Yan tails.

Improved Standard-Model prediction for K L → ℓ + ℓ −
Journal of High Energy PhysicsWe 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 ...

FCNC charmed-hadron decays with invisible singlet particles in light of recent data
Journal of High Energy Physics, 2023 The flavor-changing neutral current (FCNC) decays of charmed hadrons with missing energy (Ɇ) can serve as potentially promising hunting grounds for hints of new physics, as the standard-model backgrounds are very suppressed.

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

Uniting low-energy semileptonic and hadronic anomalies within SMEFT
Journal of High Energy PhysicsTwo 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 K decays in the standard model [PDF]
, 2007 The very clean theoretical predictions for the rare decays K --> pi nu nu_bar and KL --> pi0 l+ l- are reviewed, and their various theoretical inputs summarized.
