چکیده
In the present work, $k_T$-factorization formalism is applied to compute exclusive dilepton production by timelike Compton scattering (TCS) in $eA$, $pA$ and $AA$ collisions. The nuclear effects are investigated considering heavy light ions. cross section terms of invariant mass rapidity distribution lepton pair shown. analysis done for electron-ion collisions at Large Hadron-Electron Collider (LHeC), its high-energy upgrade (HE-LHeC) Future Circular (FCC) lepton-hadron mode. Additionally, ultraperipheral ion future runs Hadron (LHC) FCC (hadron-hadron mode) also considered.

Dilepton Production in Relativistic Heavy Ion Collisions
The present status of our understanding of low mass dilepton production in relativistic heavy ion collisions is discussed. The focus of the discussion will be the sensitivity of dilepton measurements to in medium changes of hadrons and the restoration of chiral symmetry. We will finally discuss how the presence of strong long wavelength pion modes, i.e. disoriented chiral condensates can be see...
متن کاملDilepton production in ultrarelativistic heavy-ion collisions.
Many probes have been proposed to map out the behaviour of hot and dense hadronic matter and also to highlight its eventual transition to a plasma of quarks and gluons. It is outside the scope of this talk to review them all or even partially: we will concentrate on electromagnetic radiation and more specifically on the emission of thermal lepton pairs. Those suffer minimal final state interact...
متن کاملTimelike Compton Scattering in Ultraperipheral Collisions
Exclusive photoproduction of dileptons, γN → ll N , is and will be measured in ultraperipheral collisions at hadron colliders. We demonstrate that the timelike deeply virtual Compton scattering (TCS) mechanism γq → llq, where the lepton pair comes from the subprocess γq → γ∗q, dominates in some accessible kinematical regions, thus opening a new way to study generalized parton distributions (GPD...
متن کاملSoft dilepton production in relativistic heavy-ion collisions.
Production of electron-positron pairs with invariant masses less than 300 MeV from thermalized hadronic matter in relativistic heavy ion collisions is calculated using a soft virtual photon approximation. The general theoretical framework is reviewed and extended to include arbitrarily massed and charged reaction partners, which we apply to pions and quarks. This result, exact within the soft p...
متن کاملMinijet-associated dilepton production in ultrarelativistic heavy ion collisions.
Dilepton production associated with minijets is calculated in ultrarela-tivistic heavy ion collisions using the first order approximation of the dilepton fragmentation functions of quarks and gluons. The full QCD evolution of the fragmentation functions is also studied. We find that the dilepton pairs from the fragmentation of minijets are comparable to direct Drell-Yan at √ s = 200 AGeV for sm...
