Analytical solution for QCD QED evolution
Daniel de Florian, Lucas Palma Conte
We present an analytical solution for the evolution of parton distributions incorporating mixed-order QCD QED corrections, addressing both polarized and unpolarized cases…
NNLO Global Analysis of Polarized Parton Distribution Functions
Ignacio Borsa, Daniel de Florian, Rodolfo Sassot +2
We present a next-to-next-to-leading order (NNLO) global QCD analysis of the proton's helicity parton distribution functions (PDFs), the first of its kind. To obtain the distributi…
The polarized photon distribution function
Daniel de Florian, Lucas Palma Conte, Gabriel Fernando Volonnino
We employ the LuxQED approach to compute the polarized photon PDF (photon pPDF). This approach expresses the pPDF in terms of the structure functions and . Different mod…
Higgs production at RHIC and the positivity of the gluon helicity distribution
Daniel de Florian, Stefano Forte, Werner Vogelsang
We show that the negative polarized gluon distribution found in a recent global next-to-leading order QCD analysis of the nucleon helicity structure is incompatible with the…
