\Delta\eta\Delta\phi\ angular correlations in pp collisions at the LHC registered by the ALICE experiment

Understand

We report on studies of two-particle \Delta\eta\Delta\phi\ angular correlations measured in proton-proton collisions at center of mass energies sqrt{s} = 0.9 TeV, sqrt{s} = 2.76 TeV and sqrt{s} = 7 TeV registered by the ALICE experiment at LHC.

• We present the dependence of the correlation function on the pair transverse momentum, the multiplicity of the event and the charge combination of particles in the pair.
• \Delta\eta\Delta\phi correlations are expected to exhibit several structures which arise from different physics mechanisms.
• The results are also related to the correlations obtained by femtoscopic analysis.
