Abstract

Measurement of the inclusive muon differential cross section with the ATLAS detector at LHC

Highlights

The spectrum of muons produced close to the interaction point in pp interactions is sensitive to heavy flavour production in the range 4 < pT < 100 GeV
A measurement in this region is useful to optimise theoretical computations and Monte Carlo generators to improve the modeling of the heavy flavour production mechanism
Nowadays theoretical computations from pQCD [1] are available allowing predictions of the muon spectrum from the QCD lagrangian and data-driven non perturbative corrections, dependent upon fragmentation function extracted from LEP data and heavy flavours decays and form factors extracted from B-factories

Summary

Introduction

The spectrum of muons produced close to the interaction point in pp interactions is sensitive to heavy flavour production in the range 4 < pT < 100 GeV. Nowadays theoretical computations from pQCD [1] are available allowing predictions of the muon spectrum from the QCD lagrangian and data-driven non perturbative corrections, dependent upon fragmentation function extracted from LEP data and heavy flavours decays and form factors extracted from B-factories. These calculations have been performed at Next to Leading Order (NLO) + Next to Leasing Log (NLL). The results presented here have been published in [2]
