Title: Measurement of the φ*η distribution of muon pairs with masses between 30 and 500 GeV in 10.4 fb-1 of pp¯ collisions

Abstract

We present a measurement of the distribution of the variable φ*η for muon pairs with masses between 30 and 500 GeV, using the complete run II data set collected by the D0 detector at the Fermilab Tevatron proton-antiproton collider. This corresponds to an integrated luminosity of 10.4 fb–1 at √s = 1.96 TeV. The data are corrected for detector effects and presented in bins of dimuon rapidity and mass. The variable φ*η probes the same physical effects as the Z/γ* boson transverse momentum, but is less susceptible to the effects of experimental resolution and efficiency. These are the first measurements at any collider of the φ*η distributions for dilepton masses away from the Z → ℓ+ℓ– boson mass peak. As a result, the data are compared to QCD predictions based on the resummation of multiple soft gluons.

FIG. 1 FIG. 1: Illustration in the plane transverse to the beam direction of the variables defined in the text and used to analyse the dilepton transverse momentum. The variables $a_{T}$ and $a_{L}$ correspond to the decomposition of $p^{ℓℓ}_{T}$ into two orthogonal components relative to the dilepton thrust axis $\hat{t}$, as illustrated.
