Invariant mass M(K$\pi$) in the $p_{\rm{T}}$ intervals [1,2], [5,6] and [16,24] GeV/c as obtained from ~100M events MB in pp collisions at $\sqrt{s}$ = 8 TeV. The blue curve shows the fit function of a combined signal (gaussian) and background function (exponential), the red dashed line represents the background fit function and the gray dash-dotted line represents the background without the reflection contribution.
Detail description
The invariant mass plot is obtained with standard Dzero topological cuts and single track cuts. kINT7 trigger is used over periods LHC12a,b,c,d,e,f,g,h,i.
