What has the LHC told us about the electroweakino sector of the Minimal Supersymmetric Standard Model?

Peter Athron, Csaba Balázs, Andy Buckley +19

We perform global fits of the electroweak sector of the Minimal Supersymmetric Standard Model (MSSM) using a comprehensive set of LEP searches, 34 Run 2 LHC searches, and 63 Run 2…

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…

HyperIso: A general BSM calculator for flavour observables

T. Reymermier, N. Fardeau, F. Mahmoudi

We present HyperIso, a new standalone program for the evaluation of flavour physics observables across a wide variety of Standard Model (SM) and Beyond-the-Standard-Model (BSM) sce…

Leptonic flavour transfer: a new window on flavour gauge symmetries

L. Darmé, N. Fardeau, F. Mahmoudi +1

New flavour non-abelian gauge groups, which may arise as part of a fundamental theory of flavour, can lead to distinctive flavour-transfer processes. When restricted to the lepton…

$Λ_{b} \to Λ$ Form Factors from Light-Cone Sum Rules with $Λ$ -Baryon Distribution Amplitudes

F. Mahmoudi, D. Mishra

We compute the $Λ_{b} \to Λ$ transition form factors using light-cone sum rules based on $Λ$ -baryon distribution amplitudes, including contributions up to twist--6. The analysis is p…

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…

Global fits and the search for new physics: past, present and future

Peter Athron, Csaba Balázs, Jon Butterworth +15

In this work, we review the history and current role of global fits in the search for physics beyond the Standard Model~(BSM), including precision tests of the Standard Model (SM).…

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…

The LHC has ruled out Supersymmetry -- really?

L. Constantin, S. Kraml, F. Mahmoudi

Despite early hopes that the Large Hadron Collider (LHC) would quickly unveil supersymmetric particles, none have been detected to date. This review examines the impact of the LHC…

Reinterpretation and preservation of data and analyses in HEP

Jon Butterworth, Sabine Kraml, Harrison Prosper +145

Data from particle physics experiments are unique and are often the result of a very large investment of resources. Given the potential scientific impact of these data, which goes…

Kaon Physics: A Cornerstone for Future Discoveries

Jason Aebischer, Atakan Tugberk Akmete, Riccardo Aliberti +153

The kaon physics programme, long heralded as a cutting-edge frontier by the European Strategy for Particle Physics, continues to stand at the intersection of discovery and innovati…

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…

Overview of $B \to K^{(*)} ℓℓ$ Theoretical Calculations and Uncertainties

F. Mahmoudi, Y. Monceaux

The search for New Physics (NP) beyond the Standard Model (SM) has been a central focus of particle physics, including in the context of $B$ -meson decays involving $b \to s \ell \e…
