Measurement of the differential cross sections for isolated direct photon pair production in pp? collisions at s = 1.96 TeV
Original language description
We present measurements of direct photon pair production cross sections using 8.5 fb1 of data collected with the D0 detector at the Fermilab Tevatron pp? collider. The results are presented as differential distributions of the photon pair invariant massd?/dM??, pair transverse momentum d?/dp??T, azimuthal angle between the photons d?/d????, and polar scattering angle in the Collins-Soper frame d?/d|cos?*|. Measurements are performed for isolated photons with transverse momenta p?T>18 (17) GeV for the leading (next-to-leading) photon in pT, pseudorapidities |??|<0.9, and a separation in ?? space ?R??>0.4.
