Electroreduction of Cu (II) and Se (IV) ions on Vitreous Carbon Electrode

Eurasian Chemico-Technological Journal, 2009
The electroreduction of copper (II) and selenium (IV) ions on vitreous carbon electrode from sulfate electrolyte has been studied. The studies have shown that during the concurrent reduction copper is first reduced within 0.15-0.05 V range of potentials.

Dalitz decays $D_{sJ}^{(*)}\to D_s^{(*)}{\ell }^{+}{\ell }^{-}$

Physical Review, 2023
The Dalitz decays of the positive-parity DsJ(*) charmed mesons, DsJ(*)→Ds(*)ℓ+ℓ− with J=0, 1, 2 and ℓ=e, μ, are important processes to investigate the nature of the DsJ(*) states. We analyze the full set of decays, considering the four lightest DsJ(*) mesons as belonging to the heavy quark spin doublets sℓP=12+ and 32+, with sℓP the spin parity of the ...

MOS CCDs for the wide field imager on the XEUS spacecraft [PDF]

, 2005
In recent years the XEUS mission concept has evolved and has been the subject of several industrial studies. The mission concept has now matured to the point that it could be proposed for a Phase A study and subsequent flight programme.

Vector meson spectral function in a dynamical AdS/QCD model

European Physical Journal C: Particles and Fields, 2022
By using gauge/gravity duality, we calculate the spectral function of the heavy vector mesons with the presence of an intense magnetic field in a hot and dense medium.

MoS₂ decoration by Mo-atoms and the MoS₂-Mo-graphene heterostructure: a theoretical study.

Physical chemistry chemical physics : PCCP, 2015
Here we propose a completely new covalent heterostructure based on graphene and self-decorated MoS2 monolayers. Detailed investigation of the decoration process of the MoS2 surface by Mo adatoms was performed using first principles DFT methods. Comparison between valence-only and semicore pseudopotentials was performed to correctly describe the ...

Configuration entropy of ϒ(1S) state in strong coupling plasma

Physics Letters B, 2023
To better understand the effects of strong coupling and QCD at high temperature in QGP, by using holographic model, we investigate the dissociation effect of bottomonium under the higher-order curvature corrections to the supergravity action ...

Enhanced $B_q\to \ell {\ell }^{\prime }$ and $B\to (K,\pi )\ell {\ell }^{\prime }$ in light of $(g-2{)}_{\mu }$

Physical Review, 2023
We study lepton flavor violating (LFV) B decays in a general two Higgs doublet model with sub-TeV exotic scalars. Two different parameter spaces are explored: one dominated by extra top Yukawa coupling ρtt, the other by LFV couplings relevant for the muon g−2 anomaly. In the first case, flavor constraints such as ℓ→ℓ′γ, h→ℓℓ′ imply LFV B decays are far

Precise measurement of the branching fractions of $J/\psi \to \overline{\Lambda }{\pi }^{+}{\Sigma }^{-}+c.c.$ and $J/\psi \to \overline{\Lambda }{\pi }^{-}{\Sigma }^{+}+c.c.$

Physical Review, 2023
Based on a data sample of (10087±44)×106 J/ψ events collected with the BESIII detector, the branching fraction of J/ψ→Λ¯π+Σ−+c.c. is measured to be (1.221±0.002±0.038)×10−3, and the branching fraction of its isospin partner mode J/ψ→Λ¯π−Σ++c.c. is measured to be (1.244±0.002±0.045)×10−3 with improved precision.
