Double D-meson production in proton-proton and proton-lead collisions at the LHC

Understand

We consider the simultaneous production of two heavy-flavoured hadrons - particularly D mesons - at the LHC.

• We base our calculations on collinearly factorized QCD at next-to-leading order, using the contemporary parton distribution functions and D-meson fragmentation functions.
• The contributions of double-parton scatterings are included in the approximation of independent partonic interactions.
• Our framework benchmarks well with the available proton-proton data from the LHCb collaboration giving us confidence to make predictions for proton-lead collisions.
