LHCb: Measurement of $D^{\pm}$ Production Asymmetry at LHCb
Heavy quark production in 7 TeV pp collisions at the LHC need not be flavour symmetric. Here the production asymmetry, $A_p$ , between $D_s^+$ and $D_s^-$ mesons is measured using the $\phi\pi$ decay mode. The difference between $\pi^+$ and $\pi^-$ detection efficiencies is measured using the ratio...

| description | Heavy quark production in 7 TeV pp collisions at the LHC need not be flavour symmetric. Here the production asymmetry, $A_p$ , between $D_s^+$ and $D_s^-$ mesons is measured using the $\phi\pi$ decay mode. The difference between $\pi^+$ and $\pi^-$ detection efficiencies is measured using the ratio of fully reconstructed to partially reconstructed $D^*$ decays. Using 1 fb$^{-1}$ of data collected with the LHCb detector, we find $A_p = (-0.39 \pm 0.22 \pm 0.08)$%. |
