Systematics in the invariant mass analysis of D*+ mesons in SNN=2.76 TeV Pb-Pb collisions in ALICE

Abstract

Using a multidimensional approach, we provide better systematic uncertainties in the analysis of the D*+meson in the D*+ -> D0 +pi+ -> K- +pi+ + pi+ decay channel. This method automates a lengthy process that used to be done by hand and also gives a new method to observe the stability of fits to invariant mass plots.
