Comprehensive analysis of local and nonlocal amplitudes in the B 0 → K *0 μ + μ − decay

open access: yesJournal of High Energy Physics
A comprehensive study of the local and nonlocal amplitudes contributing to the decay B 0 → K *0(→ K + π − )μ + μ − is performed by analysing the phase-space distribution of the decay products.

New physics searches in flavour physics

open access: yesIl Nuovo Cimento C, 2011
The origin of flavour and CP violation is among the most important open questions in particle physics. Imminent results from the LHC as well as planned dedicated flavour physics experiments might help to shed light on this puzzle. This talk concentrates on the NP sensitivity of the rare B decays B(s,d) -> mu+ mu- and B -> K* mu+ mu- and of the CP

In Vivo Microplastic Detection With Photoacoustic Imaging

open access: yesAdvanced Science, EarlyView.
ABSTRACT Microplastics are posing an escalating threat to both ecological systems and human health. Yet, current methods for investigating their bioaccumulation are highly invasive, requiring destructive analysis of ex vivo tissues via mass spectrometry, dye labelling, or Raman microspectroscopy.

Analysis of Λ b 0 $$ {\Lambda}_b^0 $$ → pK − μ + μ − decays

open access: yesJournal of High Energy Physics
The differential branching fraction and angular coefficients of Λ b 0 $$ {\Lambda}_b^0 $$ → pK − μ + μ − decays are measured in bins of the dimuon mass squared and dihadron mass.

A Perspective on Interactive Theorem Provers in Physics

open access: yesAdvanced Science, EarlyView.
Into an interactive theorem provers (ITPs), one can write mathematical definitions, theorems and proofs, and the correctness of those results is automatically checked. This perspective goes over the best usage of ITPs within physics and motivates the open‐source community run project PhysLean, the aim of which is to be a library for digitalized physics

Measurement of the branching fraction ratio R K at large dilepton invariant mass

open access: yesJournal of High Energy Physics
A test of lepton universality between muons and electrons is performed using B + → K + ℓ + ℓ − decays (where ℓ = e, μ), in the dilepton invariant-mass-squared region above 14.3 GeV2 /c 4.

Photonic Time Crystals and Time‐Varying Electromagnetic Metamatter: A New Direction for Ultrafast Tunable Photonic and Microwave Materials and Devices

open access: yesAdvanced Science, EarlyView.
Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...

eQTL Meta‐Analysis Reveals Conserved and Population‐Specific Regulatory Variation Underlying Nutritional Trait Evolution and Domestication in Tomato

open access: yesAdvanced Science, EarlyView.
A comprehensive meta‐analysis of expression quantitative trait loci (eQTLs) across five diverse tomato populations reveals a high‐resolution atlas of transcriptional regulation and uncovers conserved and population‐specific regulatory architectures underlying fruit nutritional quality traits, including flavonoids, sugars, organic acids, carotenoids ...

Integration of Spatiotemporal Multi‐Omics in Peach Fruit Unravels a Metabolic Niche and the Genetic Basis of Trichome‐Mediated Stress Adaptation

open access: yesAdvanced Science, EarlyView.
This study constructed the first spatiotemporal multi‐omics map of peach fruit and discovered a key candidate gene that synergistically regulates trichome development and drought tolerance through the jasmonic acid signaling pathway, providing insights into the coupling mechanism between development and stress resistance.
