LCSR predictions for bs hadronic form factors / Monceaux, Yann (IP2I, Lyon) ; Carvunis, Alexandre (IP2I, Lyon) ; Mahmoudi, Farvah (IP2I, Lyon ; CERN)
We address the calculation of mesonic BP form factors where P is a light pseudoscalar meson using Light-Cone Sum Rules with B-meson distribution amplitudes, and present preliminary resultsfor BK form factors at zero momentum transfer..

Kaon rare decays: theory overview / Neshatpour, Siavash (IP2I, Lyon) ; D'Ambrosio, Giancarlo (INFN, Naples) ; Iyer, Abhishek (Indian Inst. Tech., New Delhi) ; Mahmoudi, Farvah (IP2I, Lyon ; CERN ; IUF, Paris) /ATLAS Collaboration
In this proceeding, we review the current theoretical landscape of rare Kaon decays, focusing specifically on flavor-changing neutral current processes. These decays provide valuable indirect avenues for exploring new physics. [...]

Theoretical implications for a new measurement of KLπ0 / D'Ambrosio, G. (INFN, Naples) ; Iyer, A.M. (Indian Inst. Tech., New Delhi) ; Mahmoudi, F. (IP2I, Lyon ; CERN ; IUF, Paris) ; Neshatpour, S. (IP2I, Lyon)
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 different phenomenological analyses corresponding to different paths that may lie ahead. [...]

Overview of BK() Theoretical Calculations and Uncertainties / Mahmoudi, Farvah (IP2I, Lyon ; CERN ; IUF, Paris) ; Monceaux, Yann (IP2I, Lyon)
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 bs transitions. These transitions, mediated by flavour-changing neutral currents, are highly sensitive to small NP effects due to their suppression in the SM. [...]

The rare kaon decay K+π++ offers insights into Standard Model (SM) physics and beyond. Driven by vector form factor in the SM, it can also probe non-standard contributions. [...]

This work addresses the calculation of local form factors involved in the theoretical predictions of semileptonic B-meson decays at low q2. We present a new approach to the method of QCD light-cone sum rule with B-meson light-cone distribution amplitudes. [...]

Model independent analysis for B anomalies / Mahmoudi, Farvah (IP2I, Lyon ; CERN) ; Hurth, Tobias (U. Mainz, PRISMA) ; Martínez Santos, Diego (Santiago de Compostela U.) ; Neshatpour, Siavash (INFN, Naples)
We discuss the implications of b → sℓ+ℓ− measurements and their deviations with respect to the Standard Model predictions in a model-independent framework. We highlight in particular the impact of the recent updated measurements including the updated Bs → ϕµ+µ− branching ratios and angular observables, the recent CMS measurement of the branching ratio of Bs → µ+µ−, and the LHCb measured lepton flavour universality violating ratios and RK∗+.

Revisiting the averaged annihilation rate of thermal relics at low temperature / Arbey, A. (IP2I, Lyon ; CERN) ; Mahmoudi, F. (IP2I, Lyon ; CERN ; IUF, Paris) ; Palmiotto, M. (IP2I, Lyon)
We derive a low-temperature expansion of the formula to compute the average annihilation rate σv for dark matter in Z2-symmetric models, both in the absence and the presence of mass degeneracy in the spectrum near the dark matter candidate. We show that the result obtained in the absence of mass degeneracy is compatible with the analytic formulae in the literature, and that it has a better numerical behaviour for low temperatures. [...]

Beyond the Standard Model prospects for kaon physics at future experiments / D'Ambrosio, G. (INFN, Naples) ; Mahmoudi, F. (IP2I, Lyon ; CERN ; IUF, Paris) ; Neshatpour, S. (IP2I, Lyon)
Rare kaon decays offer a powerful tool for investigating new physics in sd transitions. Currently, many of the interesting decay modes are either measured with rather large uncertainties compared to their theoretical predictions or have not yet been observed. [...]
