Direct-photon production in inelastic and high-multiplicity proton-proton collisions at √s= 13 TeV

In this letter, we present the first measurement of direct photons at the transverse momentum of 1<pT<6 GeV/c at midrapidity |η|<0.8 in inelastic and high-multiplicity proton-proton collisions at a centre-of-mass energy of s= 13 TeV. The fraction of virtual direct photons in the inclusive v...
