Contributions from $${\Phi }_{B2}$$ ΦB2 to the B $${\rightarrow }$$ → PP decays within the QCD factorization

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
With the potential for the improvements of measurement precision, the refinement of theoretical calculation on hadronic B weak decays is necessary. In this paper, we study the contributions of B mesonic distribution amplitude $${\Phi }_{B2}$$ ΦB2 within ...

The Lattice Structure and Optical Properties of Neodymium-Doped Gadolinium Vanadate Crystals Induced by Ion Irradiation

open access: yesIEEE Photonics Journal, 2017
In recent times, the neodymium-doped gadolinium vanadate (Nd:GdVO4) crystal has attracted significant attention as one of the most valuable functional materials, but its lattice structure can be easily modified in an irradiation environment, which ...

Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.

2D transverse laser cooling of a hexapole focused beam of cold BaF molecules

open access: yesCommunications Physics
Laser cooling of molecules is a powerful technique for producing cold, slow beams for precision measurements and quantum control, yet its implementation remains challenging due to molecular complexity.

Additive Gaussian Process Regression for Predictive Design of High‐Performance, Printable Silicones

open access: yesAdvanced Engineering Materials, EarlyView.
A chemistry‐aware design framework for tuning printable polydimethylsiloxane (PDMS) for vat photopolymerization (VPP) is developed using additive Gaussian process (GP) modeling. Polymer network mechanics informs variable groupings, feasible formulation constraints, and interaction variables.

The SRG/eROSITA All-Sky Survey

open access: yesAstronomy & Astrophysics
We selected galaxy cluster candidates from the high-redshift (BEST_Z > 0.9) end of the first SRG (Spectrum Roentgen Gamma)/eROSITA All-Sky Survey (eRASS1) galaxy cluster catalogue, for which we obtained moderately deep J-band imaging data with the ...

Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere

open access: yesAdvanced Engineering Materials, EarlyView.
A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.

Review of particle physics - Particle Data Group

open access: yes, 2014
The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,062 new measurements from 721 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons.
