A measurement of dielectron production in proton–proton (pp) collisions at √ s = 13 TeV, recorded with the ALICE detector at the CERN LHC, is presented in this Letter. The data set was recorded with a reduced magnetic solenoid field. This enables the investigation of a kinematic domain at low dielectron invariant mass mee and pair transverse momentum pT,ee that was previously inaccessible at the LHC. The cross section for dielectron production is studied as a function of mee, pT,ee, and event…

The production of low-mass dielectrons and dimuons is a powerful tool for the understanding of the properties of the quark–gluon plasma (QGP) created in ultra-relativistic heavy-ion collisions. Since
Excess of Soft Dielectrons and Photons
Spectra of unbound electron–positron pairs (dielectrons, in brief) and photons from decays of parapositronia produced in ultraperipheral collisions of electrically charged objects are calculated.

TLDR
A measurement of dielectron production in proton-proton (pp) collisions at sqrt[s]=13  TeV, recorded with the ALICE detector at the CERN LHC, enables the investigation of a kinematic domain at low dielectrons (ee) invariant mass m_{ee} and pair transverse momentum p_{T,ee} that was previously inaccessible at the LHC.

Low transverse momentum photon production in proton-nucleus collisions at 18 GeV/c.
TLDR
The measured photon spectra are compared with the expected distribution of photons from {pi}{sup 0} decays and hadronic bremsstrahlung in order to search for new sources ofsoft photons at low transverse momentum and indicate no anomalous sources of soft photons in either {ital p}-Be or {italp}-W interactions at these energies.
