Eta/Pi0 ratio as function of $p_T$ measured in NSD p-Pb collisions at $\sqrt{S_{NN}}$ = 5.02 TeV.

The statistical uncertainties are shown as vertical error bars. The systematic uncertainties are represented as boxes. 

For comparison, also the Eta/Pi0 ratios measured in $\unit[7]{TeV}$ pp collisions with ALICE \cite{Abelev:2012cn}, 

in d-Au collisions at $\S_{NN}$ = 200 GeV with PHENIX \cite{PhysRevC.75.024909}, and in p-Au and p-Be collisions at

$\sqrt{S_{NN}}$ = 29.1 GeV with TAPS/CERES \cite{Agakishiev:1998mw} are shown, as well as the ratio where the $\eta$ yield is obtained 

via $m_T$ scaling from the measured $p-Pb$ $\pi^{0}$ yield.
