Transverse momentum differential inclusive crosssection of muons from heavy flavor decays in $2.5 < y < 4$, in pp collisions at $\sqrt{s}=2.76$ TeV. The verticalerror bars (open boxes) arethe statistical (systematic) uncertainties. The solid curve and the band show FONLL calculations and theoretical uncertainties, respectively. The FONLL calculations are also reported for muons from charm (long dashed curves) and beauty (dot-dashed curves) decays, separately. The lower panel shows the ratio between data and FONLL calculations.
