We obtain prompt diphoton cross section in proton-nucleus collisions in Hamiltonian light-cone approach within a hybrid approximation, treating the projectile proton in the parton model and the target nucleus in the ...

We present the full O(αS2) computation of the interference effects between the Higgs diphoton signal and the continuum background at the LHC. While the main contribution to the interference originates on the gg partonic ...

We consider the transverse-momentum (qT ) distribution of a diphoton pair pro- duced in hadron collisions. At small values of qT , we resum the logarithmically-enhanced perturbative QCD contributions up to next-to-next-to-leading ...

We study the di-photon correlations in quark-nucleus and proton-nucleus collisions at RHIC and the LHC. We show that the single fragmentation di-photon produces the away side correlations peak, and the double fragmentation ...

We consider direct diphoton production in hadron collisions, and we compute the next-to-next-to-leading order QCD radiative corrections at the fully differential level. Our calculation uses the q T subtraction formalism, ...

We study the long-range in rapidity near-side and away-side azimuthal collimation, the so-called "ridge" structure for di-photon correlations in high-energy proton-nucleus (p+A) collisions. We show that based on the ...
