Direct-photon production in inelastic and high-multiplicity proton-proton collisions at $\sqrt{s}=$ 13 TeV

ALICE Collaboration

In this letter, we present the first measurement of direct photons at the transverse momentum of $1<p_{\mathrm{T}}<6$ GeV/$c$ at midrapidity $|\eta |<0.8$ in inelastic and high-multi…
