Low-mass dilepton production in pp and AA collisions
نویسندگان
چکیده
We adopt a factorized QCD formalism to describe the transverse momentum distribution of lowmass lepton pairs produced in pp collisions, when the pair transverse momentum QT ≫ Q, with the pair’s invariant mass Q as low as Q ∼ ΛQCD. We extend this formalism to dilepton production in AA collisions by including the nuclear dependent power correction due to parton multiple scattering.

Low mass dilepton production at ultrarelativistic energies
Dilepton production in pp and Au+Au nucleus-nucleus collisions at √ s = 200 GeV as well as in In+In and Pb+Au at 158 A·GeV is studied within the microscopic HSD transport approach. A comparison to the data from the PHENIX Collaboration at RHIC shows that standard in-medium effects of the ρ, ω vector mesons compatible with the NA60 data for In+ In at 158 A·GeV and the CERES data for Pb+Au at 158...
متن کاملSame-Sign Dilepton Production via Heavy Majorana Neutrinos in Proton-Proton Collisions
We discuss same-sign dilepton production mediated by Majorana neu-trinos in high-energy proton-proton collisions pp → ℓ + ℓ ′+ X for ℓ, ℓ ′ = e, µ, τ at the LHC energy √ s = 14 TeV. Assuming one heavy Majorana neutrino of mass m N , we present discovery limits in the (m N , |U ℓN U ℓ ′ N |) plane where U ℓN are the mixing parameters. Taking into account the present limits from low energy experi...
متن کاملDilepton production in proton-proton collisions at BEVALAC energies
The dilepton production in elementary pp → eeX reactions at BEVALAC energies Tlab = 1 ÷ 5 GeV is investigated. The calculations include direct ee decays of the vector mesons ρ, ω, and φ, Dalitz decays of the π, η-, ρ-, ω-, and φ-mesons, and of the baryon resonances ∆(1232), N(1520), . . . . The subthreshold vector meson production cross sections in pp collisions are treated in a way sufficient ...
متن کاملUltra-peripheral collisions and hadronic structure
Ultra-peripheral collisions are the energy frontier for photon-mediated interactions, reaching, at the Large Hadron Collider (LHC), γ− p center of mass energies five to ten times higher than at HERA and reaching γγ energies higher than at LEP. Photoproduction of heavy quarkonium and dijets in pp and pA collisions probes the gluon distribution in protons at Bjorken-x values down to 3 × 10−6, far...
متن کاملe+e− production from pp reactions at BEVALAC energies
We have performed a detailed study of dilepton production from pp collisions including the subthreshold ρ production via baryonic resonances (N(1520), N(1700)) in addition to the conventional dilepton sources as π0, η, ω and ∆ Dalitz decays and direct decays of vector mesons (ρ, ω). The role of baryonic resonances in ρ production from nucleon-nucleon collisions is studied in comparison to the D...
