D*s investigation in pPb 2016

D*s reconstruction with:

D*_s+ -> D_s+ gamma (pi0)

Photons are reconstructed from Ecal, electron pairs (LL and DD). Merged and resolved pi0s are both included. Ds candidates are obtained from \textbf{Hlt2CharmHadDs2KKPi\_XSecTurbo} line.

Additional pre-selections are applied:

tracks: 2<\eta<5, p_{\mathrm{T}}>400 \mathrm{MeV}, \chi^2/\mathrm{ndof}<3, \mathrm{ProbNNghost}<0.3

D_s^+: \chi^2(\mathrm{VD})>50, \chi^2/\mathrm{ndof}(\mathrm{vtx})<10

\gamma: p_\mathrm{T}>350 \mathrm{MeV},\mathrm{CL}>0.7(ECAL)
