Abstract (data abstract)

CERN-LHC. The production of muons from heavy-flavour hadron decays in p--Pb collisions at $\sqrt{s_{\rm NN}}=5.02$~TeV was studied for $2<p_{\rm T}<16$~GeV/$c$ with the ALICE detector at the CERN LHC. The measurement was performed at forward (p-going direction) and backward (Pb-going direction) rapidity, in the ranges of rapidity in the center-of-mass system (cms) $2.03<y_{\rm cms}<3.53$ and $−4.46<y_{\rm cms}<-2.96$, respectively. The production cross sections and nuclear modification factors are presented as a function of transverse momentum ($p_{\rm T}$). At forward rapidity, the nuclear modification factor is compatible with unity while at backward rapidity, in the interval $2.5<p_{\rm T}<3.5$~GeV/$c$, it is above unity by more than $2\sigma$. The ratio of the forward-to-backward production cross sections is also measured in the overlapping interval $2.96<|y_{\rm cms}|<3.53$ and is smaller than unity by $3.7\sigma$ in $2.5<p_{\rm T}<3.5$~GeV/$c$. The data are described by model calculations including cold nuclear matter effects.
