“…Indeed, many years of intense experimental efforts, ranging from fixed targets [4,5,6,7,8,9,10,11] to colliders [12,13,14,15,16,17], have led to a wealth of experimental data on prompt photon production in hadronic collisions, but also to a controversial situation. In particular, in the late 90's some confusion was created by one fixed target experiment [9] which found cross sections several times above theoretical predictions based on Next-to-Leading Order (NLO) calculations; data and theory disagreed both in magnitude and shape.…”

“…There are three scales that should be set in the calculation of the cross section equation (1). For the direct part, the renormalization scale appears in perturbative partonic cross section while the (initial state) factorization scale appears in both partonic cross section and PDFs.…”

“…From past to present, prompt photon production at hadron colliders has undergone very impressive experimental [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] and theoretical developments. The experimental measurements cover a large domain of center-of-mass energy and also a wide range of photon transverse energy .…”

The prompt photon production in hadronic collisions has a long history of providing information on the substructure of hadrons and testing the perturbative techniques of QCD. Some valuable information about the parton densities in the nucleon and nuclei, especially of the gluon, can also be achieved by analysing the measurements of the prompt photon production cross section whether inclusively or in association with heavy quarks or jets. In this work, we present predictions for the inclusive isolated prompt photon production in pp collisions at center-of-mass energy of 13 TeV using various modern PDF sets. The calculations are presented as a function of both photon transverse energy and pseudorapidity for the ATLAS kinematic coverage. We also study in detail the theoretical uncertainty in the cross sections due to the variation of the renormalization, factorization, and fragmentation scales. Moreover, we introduce and calculate the ratios of photon momenta for different rapidity regions and study the impact of various input PDFs on such quantity.

“…In addition, DPP production is interesting in its own right, and is used to check the validity of the predictions of pQCD and soft-gluon resummation methods implemented in theoretical calculations. Measurements involving the diphoton final state have been previously carried out at fixed-target [53,54] and collider experiments [55][56][57] . However, the large integrated luminosity accu- [15] , DIPHOX [16] and PYTHIA [13] .…”
