Maximizing the physics potential of B±→π±μ+μ− decays (2024)
Journal Article
Marshall, A. M., McCann, M. A., Patel, M., Petridis, K. A., Reboud, M., & van Dyk, D. (2024). Maximizing the physics potential of B±→π±μ+μ− decays. Physical Review D, 109(11), https://doi.org/10.1103/physrevd.109.116013

We present a method that maximizes the experimental sensitivity to new physics contributions in 𝐵±→𝜋±⁢𝜇+⁢𝜇− decays. This method relies on performing an unbinned maximum likelihood fit to both the measured dimuon 𝑞2 distribution of 𝐵±→𝜋±⁢𝜇+⁢𝜇− decays,...

In recent years, theoretical and phenomenological studies with effective field theories have become a trending and prolific line of research in the field of high-energy physics. In order to discuss present and future prospects concerning automated to...

Prospects for searches of b → sν ν ¯ decays at FCC-ee (2024)
Journal Article
Amhis, Y., Kenzie, M., Reboud, M., & Wiederhold, A. R. (2024). Prospects for searches of b → sν ν ¯ decays at FCC-ee. Journal of High Energy Physics, 2024(1), Article 144. https://doi.org/10.1007/jhep01%282024%29144

We investigate the physics reach and potential for the study of various decays involving a b→sνν¯ transition at the Future Circular Collider running electron-positron collisions at the Z-pole (FCC-ee). Signal and background candidates, which involve... Read More about Prospects for searches of b → sν ν ¯ decays at FCC-ee.

Dispersive analysis of B → K (*) and B s → ϕ form factors (2023)
Journal Article
Gubernari, N., Reboud, M., van Dyk, D., & Virto, J. (2023). Dispersive analysis of B → K (*) and B s → ϕ form factors. Journal of High Energy Physics, 2023(12), Article 153. https://doi.org/10.1007/jhep12%282023%29153

We propose a stronger formulation of the dispersive (or unitarity) bounds à la Boyd-Grinstein-Lebed (BGL), which are commonly applied in analyses of the hadronic form factors for B decays. In our approach, the existing bounds are split into several n... Read More about Dispersive analysis of B → K (*) and B s → ϕ form factors.

Testable likelihoods for beyond-the-standard model fits (2023)
Journal Article

Studying potential BSM effects at the precision frontier requires accurate transfer of information from low-energy measurements to high-energy BSM models. We propose to use normalising flows to construct likelihood functions that achieve this transfe... Read More about Testable likelihoods for beyond-the-standard model fits.

Toward a complete description of b → uℓ − ν ¯ within the Weak Effective Theory decays (2023)
Journal Article

We fit the available data on exclusive semileptonic b → uℓ−ν¯ decays within the Standard Model and in the Weak Effective Theory. Assuming Standard Model dynamics, we find Vub=3.59−0.12+0.13×10−3. Lifting this assumption, we obtain stringent constrain... Read More about Toward a complete description of b → uℓ − ν ¯ within the Weak Effective Theory decays.
