Reconstruct ReDecay D* Inclusive MC #128

Closed afernez closed 9 months ago

afernez commented 1 year ago

I've been trying to modify our Davinci reconstruction script to be able to reconstruct the (effectively) inclusive $D^{*}$ MC (see Christos' comment in his MC request issue for an overview of the samples), which will be used to get ghost efficiencies (transfer factors between fake and real $\mu$ stripping lines) for our misID. I'm not very familiar with the software/the reconstruction code, however, and I haven't been able to figure out what needs to be changed in the code in order to successfully reconstruct events.

@hadjichris Manuel and I thought maybe this would be a good thing for you to think about. I'll try to provide some more detailed guidance than this one (vague) comment soon, but for now maybe you can just think about this a bit.

As a note: I've just been trying to reconstruct a subsample of events locally (this is what we'd standardly been doing: reconstruct a small number of events locally to make sure everything is ok before submitting a large job to the GRID). Instructions for how to do this locally are here (it requires installing Docker).

@afernez Sure. I will go over the software and documentation and we can talk more about it on Tuesday.

For Apple M1 ARM-based system users: docker-machine is now deprecated. I found Colima to be a great replacement and you can easily connect the docker daemon with a simple command:

brew install docker docker-compose docker-machine colima
colima delete
colima start --arch x86_64

Ready to docker!

docker pull umdlhcb/lhcb-stack-cc7:DaVinci-v45r6-SL

You can use ROOT:

The JIRA ticket for the MC request of EventType 11774014 can be found here. As an option file they used D02HH_TriggerFiltering.

I'll close this issue for now, since our plan is to instead request FullSim MC of 11774014, given that the ReDecay samples produced used a charm trigger. The status of this should be followed in #127 (as well as older notes from Yipeng/Svende/Manuel in #111)
