| Özet |
| A measurement of dielectron production in proton-proton (pp) collisions at , 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 (ee) invariant mass and pair transverse momentum that was previously inaccessible at the LHC. The cross section for dielectron production is studied as a function of , , and event multiplicity . The expected dielectron rate from hadron decays, called hadronic cocktail, utilizes a parametrization of the measured ratio in pp and proton-nucleus collisions, assuming that this ratio shows no strong dependence on collision energy at low transverse momentum. Comparison of the measured dielectron yield to the hadronic cocktail at and for indicates an enhancement of … |
