Rare kaon decays on the lattice

Physics Letters B, 2006
We show that long distance contributions to the rare decays K -> pi nu nu-bar and K -> pi l+ l- can be computed using lattice QCD. The proposed approach requires well established methods, successfully applied in the calculations of electromagnetic and semileptonic form factors.

Rare and Semi-Rare Decays in ATLAS [PDF]

Proceedings 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)}

Z‐Scheme Water Splitting Systems Based on Solid‐State Electron Conductors

Advanced Functional Materials, EarlyView.
This review examines the latest advances in Z‐scheme overall water splitting (OWS) systems for solar hydrogen production. These systems consist of suspended or immobilized hydrogen evolution photocatalysts (HEPs) and oxygen evolution photocatalysts (OEPs).

QED in B ¯ $$ \overline{B} $$ → K ¯ $$ \overline{K} $$ ℓ + ℓ − LFU ratios: theory versus experiment, a Monte Carlo study

Journal of High Energy Physics, 2022
Using analytic results obtained in a meson effective theory, that includes all infrared sensitive logs, we build a dedicated Monte Carlo framework to describe QED corrections in B ¯ $$ \overline{B} $$ → K ¯ $$ \overline{K} $$ ℓ + ℓ − for a generic form ...

Rare charm decays: an experimental review [PDF]

, 2012
Indirect searches, and in particular rare decays, have proven to be a fruitful field to search for New Physics beyond the Standard Model. While the down-quark sector (B and K) have been studied in detail, less attention was devoted to charm decays due to

Biodegradable and Recyclable Luminescent Mixed‐Matrix‐Membranes, Hydrogels, and Cryogels based on Nanoscale Metal‐Organic Frameworks and Biopolymers

Advanced Functional Materials, EarlyView.
The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

Probing quantum decoherence at Belle II and LHCb

Journal of High Energy Physics
With the advent of Belle II and the LHCb upgrade, the precision measurements of various B-Physics observables are on cards. This holds significant potential for delving into physics beyond the standard model of electroweak interactions.

Specific three-loop contributions to b → sγ associated with the current-current operators

Journal of High Energy Physics, 2023
We work out a specific class of three-loop diagrams (of order α s 2 $$ {\alpha}_s^2 $$ ) contributing to the decay amplitude for b → sγ associated with the current-current operators O 1 and O 2 at the physical value of the charm-quark mass m c . For many

The rare top quark decays $t\to cV$ in the topcolor-assisted technicolor model

, 2003
We consider the rare top quark decays in the framework of topcolor-assisted technicolor (TC2) model. We find that the contributions of top-pions and top-Higgs predicted by the TC2 model can enhance the SM branching ratios by as much as 6-9 orders of ...

Demonstration of an All‐Optical AND Gate Mediated by Photochromic Molecules

Advanced Functional Materials, EarlyView.
A logic AND gate that runs on photons is demonstrated. It relies on two spatially separated photochromic molecules that work in tandem. Abstract The realization of a photonic logic AND gate, i.e. a logic AND gate that runs on photons rather than electrons, and where all steps are controlled by light, is demonstrated. In a proof‐of‐principle experiment,
