B meson rare decays in the TNMSSM*

Chinese Physics C
Abstract We investigate the two loop electroweak corrections to B meson rare decays and in the minimal supersymmetry standard model (MSSM) extension with two triplets and one singlet (TNMSSM).

Coupled Ferroelectric–Photoelectrochemical in Water Reduction Over BiFeO3 Thin Film Heterostructure Modulated by Rare‐Earth Doping

Advanced Functional Materials, EarlyView.
Gd‐doped BFO (BGFO) exhibits a ∼2‐order reduction in leakage current owing to its lowest content of oxygen vacancies. This leads to a ∼2.5‐fold increase in remnant polarization. These improvements in BGFO effectively boost charge separation and transportation, resulting in the greatest incident photon‐to‐current efficiency of 12.9 ± 0.73% and a ∼1.5 ...

Rare beauty and charm decays at LHCb

EPJ Web of Conferences, 2013
Rare heavy flavor decays are an ideal place to search for the effects of potential new particles that modify the decay rates or the Lorentz structure of the decay vertices. The LHCb experiment, a dedicated heavy flavour experiment at the LHC at CERN.

Strain‐Activated Photo‐Dehalogenation Unlocks Low‐Energy One and Two‐Photon 3D Microfabrication

Advanced Functional Materials, EarlyView.
5,14‐NMI‐Cz acts, conversely to its 7,10‐NMI‐Cz(7,10‐'dibromo‐2‐(2,6‐diisopropylphenyl)‐1H‐benzo[lmn]carbazolo[9,1‐bc][2,8]phenanthroline‐1,3(2H)‐dione) counterpart, as modular photoinitiator with panchromatic photoactivity, featuring a weak C–Br bond from geometric strain for efficient Type I & II initiation. These studies demonstrate applicability of

Non-factorisable contributions of strong-penguin operators in Λ b → Λℓ + ℓ − decays

Journal of High Energy Physics
We investigate for the first time a certain class of non-factorisable contributions of the four-quark operators O $$ \mathcal{O} $$ 3−6 in the weak effective Hamiltonian to the Λ b → Λℓ + ℓ − decay amplitude.

Kaon decays at KLOE-2

EPJ Web of Conferences, 2018
I review kaon decays. I introduce the flavor problem and possible solutions. Very rare kaon decays like K→πνν¯ are very important to this purpose: we study also K→πl+l−,K→ππee where chiral dynamics is important to disentangle short distance effects.

Design of Sodium Chalcohalide Solid Electrolytes with Mixed Anions for All‐Solid‐State Sodium‐Ion Batteries

Advanced Functional Materials, EarlyView.
A novel family of sodium hafnium chalcohalide SSEs is designed with dual‐anion frameworks. Compared to the halide SSEs, the mixed anion chalcohalide framework exhibits a more compact morphology, improved thermal and mechanical properties, and enhanced electrochemical performance with different cathode materials.

CP violation in K → μ + μ − with and without time dependence through a tagged analysis

Journal of High Energy Physics
We point out that using current knowledge of B K L 0 → μ + μ − $$ \mathcal{B}\left({K}_L^0\to {\mu}^{+}{\mu}^{-}\right) $$ and B K L 0 → γγ $$ \mathcal{B}\left({K}_L^0\to \gamma \gamma \right) $$ , one can extract short-distance information from the ...

Rare B and strange decays

, 2017
Several deviations from the Standard Model predictions have been recently observed in the decays mediated by $b \rightarrow s l^+ l^-$ transitions. These could be pointing towards new vector-current contributions or could be explained by underestimated ...
