Ambidextrous light transforms for celestial amplitudes

چکیده
Low multiplicity celestial amplitudes of gluons and gravitons tend to be distributional in the coordinates $z,\bar z$. We provide a new systematic remedy this situation by studying basis light transformed boost eigenstates. Motivated novel equivalence between transforms Witten's half-Fourier twistor space, we transform every positive helicity state coordinate $z$ negative $\bar With examples, show that "ambidextrous" prescription beautifully recasts two- three-point terms standard conformally covariant structures. These are used extract examples OPE for operators. also study such at higher constructing Grassmannian representation tree-level gluon as well their transforms. The formulae $n$-point N$^{k-2}$MHV take form Euler-type integrals over regions Gr$(k,n)$ cut out energy constraints.

Models for Light-Cone Meson Distribution Amplitudes
Leading-twist distribution amplitudes (DAs) of light mesons like π, ρ etc. describe the leading nonperturbative hadronic contributions to exclusive QCD reactions at large energy transfer, for instance electromagnetic form factors. They also enter B decay amplitudes described in QCD factorisation, in particular nonleptonic two-body decays. Being nonperturbative quantities, DAs cannot be calculat...
متن کاملPolarization Patterns of Transmitted Celestial Light under Wavy Water Surfaces
This paper presents a model to describe the polarization patterns of celestial light, which includes sunlight and skylight, when refracted by wavy water surfaces. The polarization patterns and intensity distribution of refracted light through the wave water surface were calculated. The model was validated by underwater experimental measurements. The experimental and theoretical values agree wel...

متن کاملThe Meson Light - Cone Distribution Amplitudes
We give a complete re-analysis of the leading twist quark-antiquark light-cone distribution amplitudes of longitudinal and transverse mesons. We derive Wandzura-Wilczek type relations between diierent distributions and update the coeecients in their confor-mal expansion using QCD sum rules including next-to-leading order radiative corrections. We nd that the distribution amplitudes of quarks in...
متن کاملAmbidextrous leadership, ambidextrous employee, and the interaction between ambidextrous leadership and employee innovative performance
Leader opening and closing behaviors are assumed to foster high levels of employee exploration and exploitation behaviors, hence motivating employee innovative performance. Applying the ambidexterity theory of leadership for innovation, results revealed that leader opening and closing behaviors positively predicted employee exploration and exploitation behaviors, respectively, above and beyond ...
