| Abstract | We study the slow-pion relative tracking efficiency by using B 0 → D ∗ π + and B 0 → D ∗ ρ + decay modes. Owing to its limited phase space, the pion from D ∗ decay is traditionally referred to the slow-pion due to a small mass difference between the D ∗ and D 0 . We report herein a measurement of the relative tracking efficiency in the low-momentum region of 50-320 MeV performed using B 0 → D ∗ π + and B 0 → D ∗ ρ + decay modes, where the D ∗ further decays to D̄ 0 π − and ρ + decays to π + π 0 . |
