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 $K \to I ¨ ℓ^{+} ℓ^{-}$ and $K \to ℓ^{+} ℓ^{-}$ de…

Nonlocal form factor of chromomagnetic penguin in $B \to K ℓ^{+} ℓ^{-}$ from QCD light-cone sum rules

T. Hurth, A. Khodjamirian, F. Mahmoudi +3

The branching fraction of the $B \to K ℓ^{+} ℓ^{-}$ decay has been measured recently by the LHC experiments, showing a deviation from theory predictions based on the Standard Model…

Data-driven analyses and model-independent fits for present $b \to s ℓℓ$ results

T. Hurth, F. Mahmoudi, Y. Monceaux +1

We present a critical assessment of the present $B$ anomalies in the exclusive $b \to s ℓℓ$ mode based on the QCD factorisation (QCDf) approach. In particular, we analyse the…

Experimental Study of Rare Kaon Decays at J-PARC with KOTO and KOTO II

J. K. Ahn, E. Augustine, L. Bandiera +62

The rare kaon decay $K_{L} \to I ¨ ^{0} I^½ I^ˉ ½$ is extremely sensitive to new physics, because the contribution to this decay in the Standard Model (SM) is highly suppressed and known ver…

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

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 $K^{+} \to I ¨ ^{+} ℓ^{+} ℓ^{-}$

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

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