Precision physics, both at the LHC and at the EIC, requires to control the evolution of the Parton Distribution Functions to 1% accuracy. To achieve this target, we must compute the splitting kernels of the Dokshitzer-Gribov-Lipatov-Altarelli-Parisi equations to four loops in QCD. Recently, there has been significant progress towards this goal. I report the results obtained in the framework of...
We consider the extension of the MSHT20 PDFs to approximate N3LO order. We describe the inclusion of the known N3LO information and the parameterisation of the remaining missing N3LO contributions, as well as the determination of the theoretical uncertainties from missing pieces and their interpretation. We then examine the impact on the PDFs as well as on predicted cross-sections. Finally, if...
We extend the existing next-to-next-to-leading (NNLO) NNPDF sets of parton distributions to approximate next-to-next-to-next-to-leading N3LO, as required by the recent availability of an increasing number of computations of scattering processes at this order.
Given the lack of full knowledge of the N3LO splitting functions, we construct an approximation to them which includes all the...
Proton-proton collisions at the LHC generate a high-intensity collimated beam of neutrinos in the forward direction, up to energies of several TeV. The observation of these neutrinos by FASER$\nu$ and SND@LHC, and the proposal of a purpose-built Forward Physics Facility (FPF) for the High-Luminosity LHC (HL-LHC), motivate scientific inquiries of this hitherto unavailable particle beam. The...
ePIC is the EIC project detector designed to cope with the whole physics scope at EIC. It is the result of a more than ten year-long effort, which includes a set of preliminary detector concepts, a robust and articulated R&D program, two advanced detector architectures presented in 2021 as response to a call by the EIC hosting laboratories. More recently, a consolidation and optimization...
