Higher-order NLO initial state QED radiative corrections to e+e− annihilation revisited

Physical Review D
Radiative corrections due to initial state radiation in electron-positron annihilation are calculated within the QED structure function approach. Results are shown in the next-to-leading logarithmic approximation up to O(α4L3) order, where L=ln(s/me2) is

Precision Agriculture Technology Adoption for Cotton Production [PDF]

Many studies on the adoption of precision technologies have generally used logit models to explain the adoption behavior of individuals. This study investigates factors affecting the number of specific types of precision agriculture technologies adopted ...

Coulomb corrections for coherent neutrino nucleus scattering

Journal of High Energy Physics
In this work we consider sub-leading O(Z 2 α 3) corrections to coherent elastic neutrino nucleus scattering (CEvNS). These corrections are not negligible by power counting since nuclei with large coherent cross sections have sizeable nuclear charges e.g.

Structure-dependent QED in B − → ℓ − ν ¯ γ $$ {B}^{-}\to {\ell}^{-}\overline{\nu}\left(\gamma \right) $$

Journal of High Energy Physics
Based on explicitly gauge invariant interpolating operators we compute complete next-leading order QED-corrections for leptonic decays. These are sizeable since the helicity-suppression in V-A interactions allows for structure-dependent collinear logs ...

Combining QED and approximate ${\rm N}^3$LO QCD corrections in a global PDF fit: MSHT20qed_an3lo PDFs

SciPost Physics
We present the MSHT20qed_an3lo parton distribution functions (PDFs). These result from the first global PDF analysis to combine QED and approximate $N^3$LO (a$N^3$LO) QCD corrections in the theoretical calculation of the PDF evolution and cross sections ...

An Examination of the Effectiveness of Precision Teaching [PDF]

, 2009
This research examined the effect of adding precision teaching to an already used method of times table practice, compared practice with and without precision teaching, and finally compared precision teaching to rate building.

The photon content of the neutron

Journal of High Energy Physics
In this work, we complete our CT18qed study with the neutron’s photon parton distribution function (PDF), which is essential for the nucleus scattering phenomenology. Two methods, CT18lux and CT18qed, based on the LUXqed formalism and the DGLAP evolution,
