Added line for Bc+ -> Ds2* (-> D0 (-> K- pi+) K+) mu+ mu- decay, in addition SSLine is added too.

TBD:

• tune the rate
• check the efficiency on MC

requested review from @yitang, @yusong, and @mbirch

Hi @nsahoo. The rate of StrippingBc2Ds2MuMu_SSLine is 0.000. Can you try more events to estimate its rates? If production of MC used to estimate efficiency is completed?

changed milestone to %2023 Re-Strip Campaign -- Development and Testing

removed all-slots label

@nsahoo It's likely this is just a really low rate line, but could you try running a 50k/100k event test just to ensure? (right now we only see 1 event)

added all-slots label

Given the high uncertainty on the Rate,% could I ask that this MR is tested on 100 kevents and not 10 kevents?

Hi @fredi this is what @ngrieser also asked for, and the rate with 100k was reported above. For completeness, here it's:

I'm gonna do some tuning today and the MR should be in principle ready by tomorrow to get merged.

@nsahoo have you finished with your developments here? If so, could you update the rates in the header to the most recent ones, and mark as ready so that it can be review?

@ngrieser apologies for the delay. I am now running the scripts to get the updated rates, the MR is gonna be ready in next few mins.
