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

open access: yesJournal 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.

Potential of discovering Ξcc+ in Λb decays

open access: yesPhysics Letters B
We propose to search for Ξcc+ in the decay Λb→Ξcc+D−, which serves as a tagged and reconstructible source of Ξcc+. A possible fully charged final state is [(pK−K−π+)Ξc0π+]Ξcc+(K+π−π−)D−, where the subscripts indicate the parent hadron in the decay chain.

Rare Kaon Decays

open access: yes, 2011
Rare Kaon decays provide sensitive probes of short distance physics. Among the most promising modes are the K+ --> pi+ nu anti-nu and K(L) --> pi0 nu anti-nu modes due to their theoretical cleanness and the dedicated experiments, NA62 and KOTO. The key to the success of New Physics searches in these modes is the precision in the standard model ...

Assembling a True “Olympic Gel” From over 16 000 Combinatorial DNA Rings

open access: yesAdvanced Materials, EarlyView.
Olympic gels are an elusive class of soft matter, consisting of molecular networks held together purely by mechanically interlocked rings. Their topological structure promises unique properties and functions, but their synthesis has proven notoriously difficult.

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

open access: yesJournal 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 ...

Kaon Rare Decays

open access: yes, 2001
Recent results and future prospects in the rare kaon-decay experiments at KEK, BNL, CERN and FNAL are reviewed. Emphasis is placed on the quark flavor dynamics in the flavor-changing neutral current processes. Experimental and data-analysis techniques developed in the rare decay experiments are discussed.

All‐Optical Reconfigurable Physical Unclonable Function for Sustainable Security

open access: yesAdvanced Materials, EarlyView.
An all‐optical reconfigurable physical unclonable function (PUF) is demonstrated using plasmonic coupling–induced sintering of optically trapped gold nanoparticles, where Brownian motion serves as a robust entropy source. The resulting optical PUF exhibits high encoding density, strong resistance to modeling attacks, and practical authentication ...

Clustomesogen Showing Sub‐Zero Liquid Crystal Properties: Supramolecular Assembly Between Cs2[Mo6Ii8(OCOC2F5)6] and Hexaethylenoxide Containing Mesogenic Dimers

open access: yesAdvanced Materials, EarlyView.
Associating a red‐NIR phosphorescent octahedral hexanuclear molybdenum cluster compound with hexaethyleneoxide chains bearing mesogenic units on both ends leads to an emissive hybrid liquid crystal showing mesomorphism on a very unusual temperature range down to −25°C.

Improved analysis of rare Z-boson decays into a heavy vector quarkonium plus lepton pair

open access: yesNuclear Physics B
We improve the theoretical predictions for rare Z-boson decays, Z→Vℓ+ℓ− (ℓ=e or μ), where V denotes a heavy vector quarkonium including J/Ψ, Ψ(2S), and Υ(nS) with n=1,2,3.
