“…The results are compatible with the experiments and(or) the other theoretical predications [21]. Nevertheless, there are still some processes which are not well described [20,22]. We wish the higher order corrections from the higher conformal spin may give us more accurate estimates.…”

“…Our calculation concerns LCDAs to twist-6 to the accuracy of the leading order of conformal spin expansion. The obtained parameters are also used to analyze some hadronic physics processes as applications [20][21][22][23]. However, some of the investigations [20,22] have implied that corrections from the higher order conformal spin contributions may affect the results to some extent.…”

The light-cone distribution amplitudes (LCDAs) of the Σ ± baryons up to twist-6 are investigated on the basis of the QCD conformal partial wave expansion approach.The calculations are carried out to the next-to-leading order of conformal spin accuracy. The nonperturbative parameters relevant to the LCDAs are determined in the framework of the QCD sum rule method. The explicit expressions of the LCDAs are given as the main results.

“…In the past two decades, some theoretical investigations about EMFFs in both space-like (SL) and time-like (TL) regions [14][15][16][17][18][19] and a lot of experimental results on EMFFs of baryons [20][21][22][23][24][25][26][27][28][29][30][31][32] and mesons [33][34][35][36] have appeared. The SL region EMFFs of Λ and Σ were calculated in the framework of light-cone sum rule (LCSR) up to twist 6 [37,38]. It was found that the Q 2 -dependent magnetic form factor of Λ approaches zero faster than the dipole formula with the increase of Q 2 .…”

The heavy baryon Λ b is regarded as composed of a heavy quark and a scalar diquark which has good spin and isospin quantum numbers. In this picture, we calculate the electromagnetic (EM) form factors of Λ b in the Bethe-Salpeter equation approach. We find that the shapes of the EM form factors of Λ b are similar to those of Λ, which have a peak at about ω = 1, but the amplitudes are much smaller than those of Λ.

The Mechanism of Piezocatalysis: Energy Band Theory or Screening Charge Effect?

et al. 2021

Piezocatalysis, a newly emerging catalysis technology that relies on the piezopotential and piezoelectric properties of the catalysts, is attracting unprecedented research enthusiasm for applications in energy conversion, organic synthesis, and environmental remediation. Despite the rapid development in the past three years, the mechanism of piezocatalysis is still under debate. A fundamental understanding of the working principles of this technology should enable the future design and optimization of piezocatalysts. Herein, we provide an overview of the two popular theories used to explain the observed piezocatalysis: energy band theory and screening charge effect. A comprehensive discussion and clarification of the differences, relevance, evidence, and contradiction of the two mechanisms are provided. Finally, challenges and perspectives for future mechanistic studies are highlighted. Hopefully, this Review can help readers gain a better understanding of piezocatalysis and enable its application in their own research.
