Improving lepton flavour universality tests with $K_{L}$ decays

G. D'Ambrosio, A. M. Iyer, F. Mahmoudi +1

Rare kaon decays provide sensitive probes of the flavour structure of the Standard Model and of possible new physics. We perform a global analysis incorporating recent experimental…

Probing scalar and pseudoscalar new physics using rare kaon decays

G. D'Ambrosio, A. M. Iyer, F. Mahmoudi +1

Rare kaon decays provide sensitive tests of new physics. In this work, we focus on scalar and pseudoscalar operators, analysing the $K \to π ℓ^{+} ℓ^{-}$ and $K \to ℓ^{+} ℓ^{-}$ dec…

Theoretical implications for a new measurement of $K_{L} \to π^{0} ℓℓ$

G. D'Ambrosio, A. M. Iyer, F. Mahmoudi +1

Kaon physics is at an important experimental juncture with respect to the ongoing measurements of several observables. This work will build on the existing status by formulating di…

Exploring scalar contributions with $K^{+} \to π^{+} ℓ^{+} ℓ^{-}$

G. D'Ambrosio, A. M. Iyer, F. Mahmoudi +1

The rare kaon decay $K^{+} \to π^{+} ℓ^{+} ℓ^{-}$ offers insights into Standard Model (SM) physics and beyond. Driven by vector form factor in the SM, it can also probe non-standard co…
