A precision relation between Γ(K → μ + μ − )(t) and B K L → μ + μ − / B K L → γγ $$ \mathcal{B}\left({K}_L\to {\mu}^{+}{\mu}^{-}\right)/\mathcal{B}\left({K}_L\to \gamma \gamma \right) $$

open access: yesJournal of High Energy Physics, 2023
We find that the phase appearing in the unitarity relation between B K L → μ + μ − $$ \mathcal{B}\left({K}_L\to {\mu}^{+}{\mu}^{-}\right) $$ and B K L → γγ $$ \mathcal{B}\left({K}_L\to \gamma \gamma \right) $$ is equal to the phase shift in the ...

Rare kaon decays revisited

open access: yesPhysics Letters B, 2004
We present an updated discussion of $K\raπ\bar{l} l$ decays in a combined framework of chiral perturbation theory and Large--$N_c$ QCD, which assumes the dominance of a minimal narrow resonance structure in the invariant mass dependence of the $ \bar{l} l$ pair.

Real‐World Longitudinal Data on the Impact of Hydroxychloroquine Blood Level Monitoring on Lupus Outcomes: Results of a Prospective Longitudinal Cohort Study

open access: yesArthritis Care &Research, EarlyView.
Objective Hydroxychloroquine (HCQ) is a cornerstone therapy in systemic lupus erythematosus (SLE), but the weight‐based dosing does not account for clinical factors that can introduce individual variability in drug metabolism and clearance. We leveraged longitudinal data from a prospective SLE cohort to identify clinical factors that predict ...

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Creep‐Induced Microstructural Evolution in an A2‐B2 Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
A 27.3Ta‐27.3Mo‐27.3Ti‐8Cr‐10Al (at.%) refractory high‐entropy alloy with precipitation‐strengthened A2‐B2 microstructure was studied by creep tests at 1030°C, which demonstrate a transition in deformation mechanisms in the range of 100–150 MPa applied stress. This is associated with changes in dislocation–precipitate interactions. Relevant deformation

Nonleptonic B-meson decays to next-to-next-to-leading order

open access: yesJournal of High Energy Physics
We compute next-to-next-to-leading order QCD corrections to the partonic processes b → c u ¯ d $$ c\overline{u}d $$ and b → c c ¯ s $$ c\overline{c}s $$ , which constitute the dominant decay channels in standard model predictions for B-meson lifetimes ...

Rare and Semi-Rare Decays in ATLAS [PDF]

open access: yesProceedings of European Physical Society Conference on High Energy Physics — PoS(EPS-HEP2019), 2020
Flavour-changing neutral-current (FCNC) processes like $b \to s\,\mu^+\mu^-$ and $B_{(s)}^0 \to \mu^+\mu^-$ are suppressed in the Standard Model (SM) and thus sensitive to New Physics (NP) effects. This contribution summarises ATLAS results from the angular analysis of the $B^0 \to K^* \mu^+\mu^-$ decay performed with LHC Run 1 data, the $\cal B(B_{(s)}
