Inspired by the recent measurement of $CP$ asymmetry in individual mode on LHCb, we study $D\to \pi\pi$ system isospin and topological analysis. The ratio between penguin tree amplitudes $P/(T+C)$ is found to be greater than two most values relative strong phase. And $D^0\to \pi^0\pi^0$ a potential reveal order $10^{-3}$, which would observed Belle II future. large might understood $t$-channel ...

This paper presents a novel and unique measure of cross-sectional uncertainty constructed from stock options on individual firms. Cross-sectional varied little between 1980 1995 subsequently had three distinct peaks—during the tech boom, financial crisis, coronavirus epidemic. has mixed relationship with overall economic activity, aggregate is much more powerful for forecasting growth. The data...

phosphorus (p), in the form of phosphate ion (pi), is a vital element contributing in biomolecule structures, metabolic reactions, signaling pathways and energy transfer within the living cells. the objective of the present study was to assess the influence of fungal infection on pi metabolism in compare to the effects of phosphate stress in arabidopsis. quantification of total p contents showe...

low phosphorous (p) availability in soils limits production of soybean [glycine max (l.) merr.] around the world. this study was conducted to determine whether exogenous expression of the rice (oryza sativa l.) phosphates transporter gene ospt2 would increase inorganic phosphates (pi) acquisition and improve yield in transgenic soybean. cotyledonary-node explants of the soybean were inoculated ...

We project onto the light front the pion's Poincaré-covariant Bethe-Salpeter wave function obtained using two different approximations to the kernels of quantum chromodynamics' Dyson-Schwinger equations. At an hadronic scale, both computed results are concave and significantly broader than the asymptotic distribution amplitude, φ(π)(asy)(x)=6x(1-x); e.g., the integral of φ(π)(x)/φ(π)(asy)(x) is...
