Anomalous broadening of the near-side jet peak in Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 2.76 TeV

Anomalous broadening of the near-side jet peak in Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 2.76 TeV

The measurement of two-particle angular correlations is a powerful tool to study jet quenching in a $p_{\mathrm{T}}$ region inaccessible by direct jet identification. In these measurements pseudorapidity ($\Delta\eta$) and azimuthal ($\Delta\varphi$) differences are used to extract the shape of the...

Zusammenfassung:The measurement of two-particle angular correlations is a powerful tool to study jet quenching in a $p_{\mathrm{T}}$ region inaccessible by direct jet identification. In these measurements pseudorapidity ($\Delta\eta$) and azimuthal ($\Delta\varphi$) differences are used to extract the shape of the near-side peak formed by particles associated to a higher $p_{\mathrm{T}}$ trigger particle ($1 < p_{\mathrm{T, trig}}
