Interfacial Polysulfide Confinement via Spatially Controlled Sulfonated Metal–Organic Polyhedra Coatings in Lithium–Sulfur Batteries

Advanced Science, EarlyView.
Spatially controlled sulfonated metal–organic polyhedra (SMOP) coating on sulfur‐loaded hollow carbon spheres form ultrathin, conformal interfacial barriers that selectively confine soluble polysulfides, stabilize sulfur redox, and suppress shuttle reactions.

New sum rules for the B c → J/ψ form factors

Journal of High Energy Physics, 2023
We derive new sum rules for the form factors of the B c → J / ψ ℓ ν ¯ ℓ $$ {B}_c\to J/\psi \ell {\overline{\nu}}_{\ell } $$ semileptonic transitions, employing the vacuum-to-B c correlation function of the J/ψ-interpolating and b → c weak currents.

Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.

Inequalities for Standard Model Yukawa couplings

Journal of High Energy Physics
We show that the Standard Model Yukawa matrices satisfy a set of simple yet nontrivial inequalities. The relations we derive are independent of the basis used to define the fermion fields, and, amongst other things, place strong constraints on the ...

Minimally modified Fritzsch texture for quark masses and CKM mixing

Journal of High Energy Physics, 2023
The Standard Model does not constrain the form of the Yukawa matrices and thus the origin of fermion mass hierarchies and mixing pattern remains puzzling.

Can Credit Rating Changes Affect Corporate Carbon Emissions? Some Evidence From the S&P 500

Business Strategy and the Environment, EarlyView.
ABSTRACT Using panel data on US S&P 500 firms from 2012 to 2024, this study examines how credit rating changes affect corporate carbon performance. Drawing on the resource‐based view and prospect theory, we show that credit rating downgrades lead to a statistically and economically significant deterioration in emission reduction scores.

Determination of B-meson distribution amplitudes from B → π, K, D transition form factors

Journal of High Energy Physics
Recent work on B → π, K and B → D form factors from lattice QCD and light-cone sum rules has made it possible to constrain the inverse moment λ B of the B-meson light-cone distribution amplitudes by performing a global fit of B → π, K, D form factors. We

CP violation of quarks in A4 modular invariance

Physics Letters B, 2019
We discuss the quark mass matrices in the A4 modular symmetry, where the A4 triplet of Higgs is introduced for each up-quark and down-quark sectors, respectively.

Toward a complete description of b → uℓ − ν ¯ $$ \overline{\nu} $$ within the Weak Effective Theory decays

Journal of High Energy Physics, 2023
We fit the available data on exclusive semileptonic b → uℓ − ν ¯ $$ \overline{\nu} $$ decays within the Standard Model and in the Weak Effective Theory. Assuming Standard Model dynamics, we find V ub = 3.59 − 0.12 + 0.13 × 10 − 3 $$ \left|{V}_{ub}\right|=

Simultaneous determination of CKM angle $\gamma$ and charm mixing parameters

, 2021
A combination of measurements sensitive to the $CP$ violation angle $\gamma$ of the Cabibbo--Kobayashi--Maskawa (CKM) unitarity triangle and to the charm mixing parameters that describe oscillations between $D^0$ and $\overline{D}^0$ mesons is performed.
