Abstract

Measurement of the differential Drell-Yan cross sections in the dilepton decay channel is presented. It is based on proton-proton collision data at 13 TeV recorded with the CMS detector at the LHC. The differential cross section in the dilepton mass range 15–3000 GeV is measured and corrected to the full phase space.

Highlights

  • Drell-Yan (DY) process [1] in hadron-hadron collisions is described in the standard model (SM) by s-channel γ∗/Z exchange

  • A measurement of DY differential cross section dσ/dm where m is the invariant mass of the dilepton pair is presented [2] in dimuon channel in the mass range 15 < m < 3000 GeV using an integrated luminosity of 2.8 f b−1 of proton-proton collision data√collected using the Compact Muon Solenoid (CMS) detector [3] at the Large Hadron Collider (LHC) at s = 13 TeV

  • The measured differential cross section is obtained using the following formula: σ = Nu (1) A · · ρ · Lint where Nu denotes the signal yield obtained after subtracting the backgrounds and applying an unfolding technique [4] to the background subtracted data in order to correct for bin-to-bin migration effect due to detector resolution and final-state Quantum electrodynamics radiation (FSR) effect
