Low mass Drell-Yan production of lepton pairs at forward directions at the LHC: a hybrid approach

Understand

We discuss Drell-Yan production of dileptons at high energies in forward rapidity region in a hybrid high-energy approach.

• This approach uses unintegrated gluon distributions in one proton and collinear quark/antiquark distributions in the second proton.
• Corresponding momentum-space formula for the differential cross sections in high-energy approximation has been derived and will be presented.
• The relation to the commonly used dipole approach is discussed.
